菩薩從兜術天降神母胎說廣普經 3.5

3.5

The Buddha told Kāśyapa: "To know the body is to know the distinction. For the sake of sentient beings, the limbs and joints from the feet to the head each have distinct names, just as the Sūtra on the Parable of the Tree says: 'Because of roots, bark, trunk, nodes, branches, and leaves, it is called a tree.' Mind, thought, consciousness, sensation, and ideation are also like this."
