As a big fig tree bears fruits all over its body, each part of the tree of devotional service bore fruit.
This tree of devotional service is not of this material world. It grows in the spiritual world, where there is no distinction between one part of the body and another. It is something like a tree of sugar, for whichever part of such a tree one tastes, it is always sweet. The tree of bhakti has varieties of branches, leaves and fruits, but they are all meant for the service of the Supreme Personality of Godhead. There are nine different processes of devotional service (śravaṇaṁ kīrtanaṁ viṣṇoḥ smaraṇaṁ pāda-sevanam arcanaṁ vandanaṁ dāsyaṁ sakhyam ātma-nivedanam), but all of them are meant only for the service of the Supreme Lord. Therefore whether one hears, chants, remembers or worships, his activities will yield the same result. Which one of these processes will be the most suitable for a particular devotee depends upon his taste.
