In ordinary breathing we absorb and extract a normal supply of prana, but by controlled and regulated breathing (generally known as Yogi breathing) we are enabled to extract a greater supply, which is stored away in the brain and nerve centers, to be used when necessary.

We may store away prana, just as the storage battery stores away electricity.

The many powers attributed to advanced occultists is due largely to their knowledge of this fact and their intelligent use of this stored-up energy.

The Yogis know that by certain forms of breathing they establish certain relations with the supply of prana and may draw on the same for what they require.

Not only do they strengthen all parts of their body in this way, but the brain itself may receive increased energy from the same source, and latent faculties be developed and psychic powers attained.
