You 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 YoganandaThrough the orifice of silence, the whole geyser of Bliss, perpetually shoots up and flows over the soul.
Paramahansa YoganandaThe spine is the highway to the Infinite. Your own body is the temple of God. It is within your own self that God must be realized.
