Sometime later, when the boys felt disturbed by the great heat of summer, they took shelter at the base of a tree that stood just like an umbrella. The Lord then said that the life of a tree is most excellent, for even while feeling pain a tree continues to protect others from heat, rain, snow and so on. With its leaves, flowers, fruits, shade, roots, bark, wood, fragrance, sap, ashes, pulp and sprouts, a tree fulfills the desires of everyone. This kind of life is ideal. Indeed, said Kṛṣṇa, the perfection of life is to act with one’s vital energy, wealth, intelligence and words for the benefit of all.
