The greatest dread of ordinary man is death, with its rude imposition interrupting fortuitous plans and fondest attachments with an unknown and unwelcome change. The yogi is a conqueror of the grief associated with death. By control of mind and life force and the development of wisdom, he makes friends with the change of consciousness called death-he becomes familiar with the state of inner calmness and aloofness from identification with the mortal body.
Paramahansa YoganandaYou must know the difference between imagination, theoretical knowledge and true realization. Could you nourish yourself by only listening to a talk on food? To know food only theoretically is to always remain hungry. You must eat to satisfy hunger. So he who seeks new doctrines continuously but does not put them into practice in his life is in continual spiritual starvation.
Paramahansa Yogananda
