Samadhi

The book distribution in Los Angeles during the six day period is transcendental samadhi. They are working in trance, not on the material platform. No common man can work so hard, it is not possible. Working without sleep means no death. Sleeping is dead condition. “Jiv jago, jiva jago, gauracanda bole, kota nidra yao maya-pisacira kole.” Your book distribution is really intoxication. (Letter to: Ramesvara  –  Calcutta 12 January, 1976)

One should engage in practical service to the Lord. In our Krsna consciousness movement, all our activities are concentrated upon distributing Krsna literature. This is very important. One may approach any person and induce him to read Krsna literature so that in the future he also may become a devotee. Such activities are recommended in this verse. Such activities will always remind the devotees of the Lord’s lotus feet. By fully concentrating on distributing books for Krsna, one is fully absorbed in Krsna. This is samadhi. (SB 10.2.37)
