“A pure devotee is constantly engaged - sometimes he chants, sometimes he hears or reads books about Krishna, or sometimes he cooks prasadam or goes to the marketplace to purchase something for Krishna, or sometimes he washes the temple or the dishes - whatever he does, he does not let a single moment pass without devoting his activities to Krishna. Such action is in full samadhi.” (Shrila Prabhupada, Bhagavad-gita, 12.2 Purport)
