Srimad Bhagwatam

SB 10.2.27 — The body [the total body and the individual body are of the same composition] may figuratively be called “the original tree.” From this tree, which fully depends on the ground of material nature, come two kinds of fruit — the enjoyment of happiness and the suffering of distress. The cause of the tree, forming its three roots, is association with the three modes of material nature — goodness, passion and ignorance. The fruits of bodily happiness have four tastes — religiosity, economic development, sense gratification and liberation — which are experienced through five senses for acquiring knowledge in the midst of six circumstances: lamentation, illusion, old age, death, hunger and thirst. The seven layers of bark covering the tree are skin, blood, muscle, fat, bone, marrow and semen, and the eight branches of the tree are the five gross and three subtle elements — earth, water, fire, air, ether, mind, intelligence and false ego. The tree of the body has nine hollows — the eyes, the ears, the nostrils, the mouth, the rectum and the genitals — and ten leaves, the ten airs passing through the body. In this tree of the body there are two birds: one is the individual soul, and the other is the Supersoul.

SB 10.2.28 — The efficient cause of this material world, manifested with its many varieties as the original tree, is You, O Lord. You are also the maintainer of this material world, and after annihilation You are the one in whom everything is conserved. Those who are covered by Your external energy cannot see You behind this manifestation, but theirs is not the vision of learned devotees.

SB 10.2.29 — O Lord, You are always in full knowledge, and to bring all good fortune to all living entities, You appear in different incarnations, all of them transcendental to the material creation. When You appear in these incarnations, You are pleasing to the pious and religious devotees, but for nondevotees You are the annihilator.

SB 10.2.30 — O lotus-eyed Lord, by concentrating one’s meditation on Your lotus feet, which are the reservoir of all existence, and by accepting those lotus feet as the boat by which to cross the ocean of nescience, one follows in the footsteps of mahājanas [great saints, sages and devotees]. By this simple process, one can cross the ocean of nescience as easily as one steps over the hoofprint of a calf.
