The Forest of Enjoyment
31
PURPORT
Material life means being fully absorbed in eating, sleeping, mating and defending. Out of these, sleep is taken very seriously. While asleep, one completely forgets the object of life and what to do. For spiritual realization, one should try to avoid sleep as much as possible. The Gosvāmīs of Vṛndāvana practically did not sleep at all. Of course, they slept some, for the body requires sleep, but they slept only about two hours, and sometimes not even that. They always engaged in spiritual cultivation.  Nidrāhāra-vihārakādi-vijitau . Following in the footsteps of the Gosvāmīs, we should try to reduce sleeping, eating, mating and defending.
