The 7 Energy Bodies: Your Body of Light and How to Activate It
Updated: Oct 22
Claudiu Bulaceanu, PhD
The Body of Light is the set of energy bodies that surround and run through the physical body, each one vibrating higher than the one below it. Some traditions call it the subtle body, others the energy body or the lightbody. I have assessed these layers directly in clients for over 25 years, and in my work there are seven of them, nested inside each other and each tied to one of the seven major chakras.
This article covers what the Body of Light is, where the idea comes from, what each of the seven energy bodies does, and the practices that build it. It also covers what to avoid, because some popular habits quietly work against it.
What the Body of Light Is
The physical body is the densest layer of a larger structure, it's the body we all use and perceive it directly by our 5 senses. Around it and through it sit six finer energy bodies, each occupying about the same space as the others and vibrating at a higher rate. Energy moves through them along channels the yogic tradition calls nadis and gathers in centers called chakras. When the flow through all seven layers is clean, a person feels clear and connected to something beyond themselves. When one layer is blocked, the layers above it have less to work with.
The Body of Light acts as a bridge between the physical body and the soul. The soul does not act on the physical body directly. It acts rather through these layers, from the finest down to the densest (physical), and the quality of each layer decides how much of the soul's intent reaches daily life. This is why I treat the energy bodies as practical rather than abstract. A blocked emotional or mental body shows up in decisions and relationships long before it shows up anywhere else.
What Science Measures and What Belongs to My Framework
No instrument has detected the subtle bodies. Physics measures the electrical activity of the brain and heart, along with the magnetic field the heart produces, and I go through those measurements in my article on body vibration and how to raise it. Those are physical fields, and none of them is an energy body in the sense used here.
In medical research, the hypothesized field around living bodies is called the biofield, and researchers working on it describe biofield science as an emerging field of study. It has not established the existence of distinct energy layers.
What I describe below comes from direct assessment, the same way I assess soul and body vibration. I built and calibrated these methods over many years of practice, and they hold up consistently inside it. It is a research framework rather than established science, and I present it that way.
The Body of Light Across Spiritual Traditions
Many traditions describe something close to the Body of Light, using different names and different counts.
In ancient Egypt, a person was understood to have several spiritual aspects. The ka was a double formed at birth, the ba was shown as a bird with a human head, and the akh was the transfigured spirit a person could become after death. Egyptologists translate akh as "effective", and the word shares a root with words for shining. The akh is the closest Egyptian idea to a body of light.
In Hindu philosophy, the Taittiriya Upanishad describes five sheaths, or koshas, around the self. The second of them, the pranamaya kosha, is the energy body that carries prana (subtle energy). The wider idea of a subtle body runs through yoga and tantra.
In Tibetan Buddhism, advanced Dzogchen practitioners aim for the rainbow body, in which the physical body dissolves into light at death. Tibetan sources record reported cases of it across several centuries.
In Western esotericism, "body of light" became a name for the astral body, the vehicle used in out-of-body experience. Theosophy later arranged the human being into seven principles. In 1987, Barbara Brennan's "Hands of Light" described seven layers of the aura: the etheric body, emotional body, mental body, astral body, etheric template, celestial body and ketheric template.
My own scheme also has seven layers, and several names match Brennan's. It differs in two places that matter in practice. The first layer is the physical body itself rather than an etheric layer just outside it, and the fifth layer, which I call the ethereal body, is the threshold for physical ascension.
The 7 Energy Bodies, Layer by Layer
The seven energy bodies are contained within each other, and vibration rises from the physical body up to the seventh. Each one corresponds to a chakra, and each lines up with one band of my vibrational frequency chart. Knowing which layer is weakest tells you what to work on next.
1. The Physical Body
The physical body is the densest layer and the vehicle through which we live in a world that vibrates, on average, at the third dimension (3D, or third chakra level). It corresponds to the root chakra and the Ground band in my chart. The six finer bodies feed it with energy. In my readings, blockages held for years in the upper layers tend to reach the physical body last, as fatigue or tension the person cannot explain. That pattern is one more reason to have anything physical checked by a doctor first.
2. The Emotional Body
The emotional body holds intense emotions and desires, along with the patterns that repeat in close relationships. It corresponds to the sacral chakra and the Attachment band. Possessiveness and the fear of losing someone sit here, and so does tenderness once they clear.
3. The Mental Body
The mental body is the seat of thoughts and beliefs, and of the ego, and it shapes how a person approaches life and the reality around them. It corresponds to the solar plexus chakra and the Will band. Most limiting beliefs are anchored in this layer, which is why clearing them changes so much in the layers above.
4. The Astral Body
The astral body vibrates at the fourth dimension and corresponds to the heart chakra and the Heart band. We connect with it during sleep, and it is the body involved in out-of-body experience and in dream travel. When this layer is open, empathy and care for others come without effort.
5. The Ethereal Body
The ethereal body vibrates at the fifth dimension and corresponds to the throat chakra and the Integrity band. It governs communication in two directions: with other people, and with higher levels of vibration. Saying what is true, without hidden agendas, is the work of this layer.
6. The Celestial Body
The celestial body holds the knowledge of past lives and of the plan for the current life. It corresponds to the third eye chakra and the Wisdom band, at the sixth dimension. When the third eye is open, a person starts to see the real causes behind the situations around them rather than only the situations themselves. When someone has his third eye chara opened, he can much more easily learn his life lessons, which is actually the main purpose a soul embodies on this planet.
7. The Ketheric or sovereign Body
The ketheric body, which I also call the Sovereign Soul body, corresponds to the crown chakra and the Unity band, at the seventh dimension. It carries the connection with the Divine and the experience of oneness with Creation. A soul that lives from this layer has reached spiritual enlightenment.
How the Body of Light Connects to Ascension
Spiritual ascension means raising the vibration of the soul and of the body over time. The Body of Light is where that rise becomes visible, layer by layer. As you clear and balance the energy bodies, energy moves more freely between them, intuition becomes more reliable, and guidance from higher levels gets through with less distortion.
Two concepts are often confused here. The rainbow body concerns the first five layers, from the physical body up to the ethereal body. The full lightbody includes all seven. Practitioners who build their Body of Light up to the vibration of the ethereal body are working toward physical ascension, and in my observation this speeds up the lessons of the present life considerably. I explain how these ideas relate in that article.
Kundalini energy plays a large part in this. When it rises through channels that have already been cleansed, it activates and strengthens each energy body in turn. When it rises through blocked channels, it causes the kind of difficulties described in my article on kundalini awakening dangers.
Light Body Activation: Practices That Work
Light body activation is a gradual process, measured in years rather than weekend retreats. These are the practices I see build the energy bodies most reliably, in roughly the order I would begin them.
Grounding First
Among the people I read, the root chakra is open at around 4% on average. At that level the physical body has a weak connection to the Earth, and every layer above it rests on an unstable floor. Active grounding, practiced daily with attention and gratitude toward the Earth, comes first. I describe it in how to heal your root chakra before awakening kundalini.
Meditate and Work With the Breath
Meditation quiets the mental body enough for the finer layers to come through. Fifteen to twenty minutes a day, kept up for months, produces noticeable change. Breathwork increases the flow of prana and stimulates the energy centers, and it works best alongside meditation rather than as a replacement for it.
Release Limiting Beliefs
This is the practice that matters most. Beliefs held in the subconscious block the flow of energy and pull vibration down across several layers at once. No amount of meditation skill compensates for a physical body and energy bodies kept low by beliefs nobody has looked at. Releasing limiting beliefs cleanses the physical body and the energy bodies together.
Eat for a Higher Vibration
The physical body is the base of the whole structure, and food is one of its largest daily inputs. Simpler, fresher food keeps the base clean enough for the purification of the upper layers to hold. The full ordering is in my food vibration chart.
Receive Energy Transfers
Energy transfers from a competent spiritual guide or master, given in person or at a distance, help remove blockages and restore the flow between layers. They support the active work above and do not replace it.
What to Avoid While You Build Your Body of Light
From my own experience and from watching other practitioners, several habits undo progress faster than practice builds it.
Neglecting your diet. A heavy diet keeps pulling the physical body down, and the purification of the upper layers cannot hold on top of it.
Mixing spiritual schools. If you follow a particular school, I strongly advise against practicing procedures from other schools at the same time. Different systems work on the energy bodies in different ways, and combining them often produces the opposite of what each one intends, lowering vibration rather than raising it.
Long exposure to heavy environments. We all act as energetic antennas. Long hours in crowded, dense places take a toll over time, especially during intensive practice periods. This does not mean isolating yourself. It means noticing how much time you spend in such places and recovering afterwards, in nature if you can.
Going it alone through difficult phases. Blockages and old pain surface as the layers clear, most visibly during the dark night of the soul. Patience with yourself helps, and so does a competent spiritual guide who can see what is happening from outside.
Light Body Activation Symptoms
People often ask about light body activation symptoms. As the energy bodies clear, some people notice changes in sleep and dreams, stronger emotions surfacing for a while, sensitivity to crowded places, or warmth and tingling along the spine. These are tendencies I see in practice, not a checklist, and none of them proves that activation is happening.
Rule Out Medical Causes First
Every one of the sensations above also has ordinary physical causes, and those are far more common. Headaches, dizziness, palpitations, numbness, persistent fatigue or changes in mood should be checked by a physician before you look for a spiritual explanation.
Nothing in this article is medical advice, and an assessment of the energy bodies is not a diagnosis. Energy work can sit alongside medical care. It does not replace it. If you are in distress, contact a qualified professional or an emergency service in your country.
Finding Out Which Layer Holds You Back
The seven energy bodies rarely develop evenly. In most people one or two layers lag behind and hold the rest back, and guessing which ones from inside is unreliable. Each layer corresponds to a chakra, so chakra openness is the most direct way to see where the weak point is.
A full spiritual reading gives the openness of each of your seven chakras as a percentage, together with your soul and body vibration and your energy blocks. If you want to start smaller, the same page offers a free sample, "Your vibration, measured", available once per person.
If you prefer to talk it through, a private spiritual consultation covers your chakras and vibration in a live session on Zoom. For steady work on the layers over a month, with weekly scans and energetic support between sessions, there is spiritual coaching. When a reading shows beliefs holding a layer down, limiting beliefs release sessions are the next step. The 13-level program of the Body & Soul Ascension Academy teaches the methods for building the Body of Light in order.
Questions People Ask
What is the Body of Light?
It is the set of seven energy bodies that surround and run through the physical body, each vibrating higher than the one below it. It acts as the bridge between the physical body and the soul.
What are the 7 energy bodies?
In my framework they are the physical, emotional, mental, astral, ethereal, celestial and ketheric/sovereign bodies, each tied to one of the seven major chakras from root to crown.
Is the Body of Light the same as the aura?
They overlap. The aura usually refers to the field around the body corresponding to the emotional and mental bodies, that some people perceive as light or color. The Body of Light includes that fields and also all the other energy fields, including the physical body at its center.
What is the difference between the energy body and the subtle body?
Most traditions use the two terms for the same thing: the non-physical layers that carry life force. Some reserve "energy body" for the layer just above the physical, which the yogic tradition calls the pranamaya kosha.
How long does light body activation take?
It takes years of consistent practice, and the pace depends mostly on how many beliefs and blockages there are to clear. Grounding and belief release shorten it more than any other practice.
Can I see or measure my energy bodies?
No device measures them. I assess them directly, and the chakra openness percentages in a spiritual reading show which layer needs attention first.
Where to Start
Begin with grounding and with the beliefs that keep your mental body heavy, since every layer above rests on those two. If you want to know which of your energy bodies is holding the rest back, start with a reading and use it as your map.
