"The process of devotional service is a very happy one. Why? Devotional service consists of sravanam kirtanam visnoh, so one can simply hear the chanting of the glories of the Lord or can attend philosophical lectures on transcendental knowledge given by authorized acaryas. Simply by sitting, one can learn; then one can eat the remnants of the food offered to God, nice palatable dishes. In every state devotional service is joyful. One can execute devotional service even in the most poverty-stricken condition. The Lord says, patram puspam phalam: He is ready to accept from the devotee any kind of offering, never mind what. Even a leaf, a flower, a bit of fruit, or a little water, which are all available in every part of the world, can be offered by any person, regardless of social position, and will be accepted if offered with love. There are many instances in history. Simply by tasting the tulasi leaves offered to the lotus feet of the Lord, great sages like Sanat-kumara became great devotees. Therefore the devotional process is very nice, and it can be executed in a happy mood. God accepts only the love with which things are offered to Him."
(Bhagavad-gita, 9.2, Purport)
