In the material world we want to minimize our activities and take rest more but in the spiritual world, there is no rest and there is no limit of activities. Krishna is unlimited, His service is unlimited, and the energy of His servants is unlimited. Although we are in the midst of ignorance, still if we keep ourselves alert there is no place of ignorance.
From Srila Prabhupada’s letter to Tamala Krsna — Hawaii 18 March, 1969
