The body becomes healthy by exercise and work; the mind becomes healthy by upasana (devout contemplation) and namasmarana (remembrance of the Divine), by regular, well-planned discipline, joyfully accepted and joyfully carried out. Ahimsa (non-injury) is the rice; arpitam (dedication) is the gram; prayaschittam (expiation) the raisins; paschattapam (repentance) is the jaggery. Mix all these well with the ghee of sadgunam (virtue). That is the offering you should make to your Ishtadevata (chosen deity), not the paltry stuff you make out of articles got for a paisa in the shops! The Gopis knew this secret passage to the heart of the Lord, and they realised Him quick and fast. You have heard that Krishna is Murali-Madhava, and what exactly is the murali? You must be the murali (the flute). Let the breath of Krishna pass through you, making delightful music that melts the hearts. Surrender yourself to Him; become hollow, without vasana (tendencies), and become egoless, and desireless; then, He will Himself come and pick you up caressingly and place you, the flute, to His Lips and blow His sweet breath through you. Allow Him to play whatever song He likes.
