Right, coming to the matter of Prana, Kundalini and Brahman. These are all Vedic terms and Vedic concepts. So it is important to see how the Vedic people understood them. The best place to look is in the Upanishads.
The Vedic people describe Prana as the life force or life energy that originates from the Self and is inseparable from the self. It is present not just in the body, but in every thing in creation. The Sun has prana, plants have prana, rocks have prana. They describe the entire universe as a network of pranic channels, pranic forces and pranic plexus points(called Chakras) It’s all prana baby. Now Prana can be quantified as more prana or less prana. The vedic people say, for example that certain objects, geometries, directions have more or less prana. The human body is described as a microcosm of creation so it too has a network of pranic channels, pranic forces and pranic plexus points. It too can either be receiving more prana or less prana.
Now there is something called Kundalini which is described as a potential cosmic energy. The word Kundalini itself means, “coiled up” very much like a spring holding potential energy. This potential energy is released gradually into the pranic circuit of the human body, as the body become more and more purified. What does this mean? It means that blockages are removed to allow the prana to flow. The natural result of this the body becomes filled with more and more pranic energy. This impacts on the “Chitta” i.e., the consciousness of the person because there is a direct relationship between prana and chitta and a result the chitta settles and one begins to experience this qualitatively as different states of consciousness. There comes a point when all the potential energy enters the human body and one becomes completely filled, the entire pranic circuit of the body lights up, and one experiences this qualitatively as infinite bliss, self-realization, communion with the divine, enlightenment, being filled with spirit.
Similarly, Kundalini exists within nature as well as an infinite and potential energy that we can extract energy from at any point in space. The amount of energy we extract, as modern physics has calculated, is so great that within the space of a cup, there is enough energy to boil all the oceans in the world. Now, boy, that is a lot of energy! Can you imagine what would happen if we learned to tap Kundalini within nature and release the infinite storehouse she has? Well, this is the energy that we are releasing into our body through our spiritual practice. This is why playing with Kundalini is dangerous as she can destroy our body if our body is not ready to receive her.
To speak of many prana - vyana, samana, udana, apana, chakras, nadis and kundalini is as absurd as speaking of many kinds of energy: potential, kinetic, light, heat, sound. It is all one universal energy. Likewise, there is only one prana and this one prana does many functions. There a prana that functions upwards, a prana that functions downwards, one that functions in our digestive system and so on. There are not several pranas as much as there are not several winds, one that blows left, one that blows right, one that blows up, one that blows down
It is all just one prana.
Finally, the Vedic people realise that prana is actually really Brahman. It is the life energy that animates the entire universe and where else can such a universal life energy emanate from. It emanates from the source itself. Brahman. Why does this life energy have an effect on chitta? That is because they are both the same substance. If they were different, then they could not affect each other. A magnet can only attract a magnetic object because both the magnet and the magnetic object contain the same substance. Likewise, the prana affects the chitta, because they are the same substance.
I think my explanations so far have been very comprehensive and well illustrated that no room for doubt should remain. Alas, I know the rest of this thread is going to continue as it is going - in 3D consciousness mode
