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.
Conserve the vital energy, follow a balanced diet, and always smile and be happy. He who finds joy within himself discovers that his body is charged with electric current, life energy, not from food but from God. If you feel that you can't smile, stand before a mirror and with your fingers pull your mouth into a smile. It is that important!
It is a great mistake to regard a certain object as pleasurable in itself and to store the idea of it in the mind in hope of fulfilling a want by its actual presence in the future. If objects were pleasurable in themselves, then the same dress or food would always please everyone, which is not the case.
