Prana.

Prana accumulates between the base of the heart and the neck. It is linked to the function of the lungs and to inspiration. The motion of prana is accumulation and expansion of the lungs and of the internal energy. When you are full of prana, you're ready for life, you're charged with energy your respiration is open and you mind takes on a sense of positivity.

Ordinary breath, the most manifest symptom of life is only the obvious aspect of prana. Like it's Chinese equivalent, chi, prana refers to a whole spectrum of subtle energies, manifesting at the coarse material level as ordinary breath in which we take the air through the nostrils. Our whole organism, not only the nostrils, participates in recieving finer alchemical substances, impressions and energies. The substances we take in from the whole field of prana depend on the depth and equality of our attention. What an accomplished yogi breaths in and utilizes is not the same substances as breathes in by a novice.
