Mother Earth as life source
Ancient spiritual texts say that we get a limited amount of prana at birth that we use up over a life. Since ancient times, spirituals searched for means on how to refuel the initial energy (prana / chi) amount so to be able to live longer, healthier and happier.
For the sake of explanation let’s say we get 100 units of vitality at birth from our parents, but actually we get the vitality from Mother Earth who’s the root source of our body elements and energy. Anyway, through life we spend bit by bit this stock of vitality. This stock of vitality the chinese spirituality say it’s stored in the 3 dantiens (lakes of energy - energy stocks) we have in our body.
During life, Earth’s lifeforce feeds each moment our bodies through the C1 (root chakra), a thing that hinduism and later yoga called it “kundalini”, but they didn’t actually realize it’s Earth lifeforce, they still think is some mysterious life energy given to humanity by a goddess called Shakti.
This Earth’s lifeforce, plus the food and drink we ingest, does refill partially the depleted stock of vitality. Of course that it doesn’t refill completely and we still lose something due to daily activities and emotions, and in 70–80 years the vital stock is completely depleted and we make the grand “exit”, it’s that simple.
Now, if we practice some energy procedures like meditation and other more specific energy procedures like grounding ones, we have the chance to bring in us higher energy and hence add some more higher energy (prana/chi) to the vitality stock, and thus delay its total depletion and so extend our lifetime and live longer and healthier… But even this thing can’t refill 100% the expended life stock so in the end our body still gets worn out and die, but just much later and in a much better condition than the average Joe.
Advanced prana refueling techniques for body immortality
To meditate and bring that much higher energy in us I use in my spiritual school of "Body & Soul Ascension Mastery" some specific energy active procedures that allow a refueling of body energy fields, which are much more powerful than meditation in general and the usual grounding techniques. These techniques help get back one’s health, ensure a safety shield against lower energies around, make someone more sensitive to energies so to navigate among life challenges, and so on.
There are even stronger energy procedures to refuel 100%+ our body energies, procedures that were used by very high souls like Babaji and Padmasambhava for instance. These entities had preserved their bodies for hundreds and even thousands of years, and use to pop in and out in front of some people to deliver certain messages.
On the other hand the techniques these souls used to preserve their bodies for so long can’t be used directly by a spiritual, but only after reaching a very high level for their body vibe by using the procedures mentioned above, and only then migrate to their techniques.
Obviously they got their chakras 100% open, and they use their lightbody as a vessel to move around, not only in space but also in time, and even between vibration dimensions.
Human bodies are very dense and made of about 50 trillion (thousands of billions) cells and so have a huge inertia in changing, and therefore they need a progression in steps, with procedures being changed along the way accordingly.
