As water by cooling and condensation becomes ice, so thought by condensation assumes physical form. Everything in the universe is thought in material form.
Paramahansa YoganandaDo your best and then relax. Let things go on in a natural way, rather than force them.
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?

So he who seeks new doctrines continuously but does not put them into practice in his life is in continual spiritual starvation.
