No one can be a yogi, maintaining a state of mental equilibrium, free from inner involvement in planned desireful activities, unless he has renounced identification with his ego and its unsatisfiable lust for the fruits of actions.

The physical ego, the active consciousness in man, should uplift its body-identified self into unity with the soul, its true nature; it should not allow itself to remain mired in the lowly delusive strata of the senses and material entanglement.

Cosmic energy enters the body through the medulla and then passes to the cerebrum, in which it is stored or concentrated.
