Shape (CC and Other Books)

CC Adi 6.14-15, Purport:
The example cited by materialists that trees automatically come from the earth follows the same principle. Taking advantage of a certain condition, a living entity comes from the earth. According to the Bṛhad-āraṇyaka Upaniṣad, every living being is forced by divine superintendence to take a certain type of body according to his past deeds. There are many varieties of bodies, and because of a divine arrangement a living entity takes bodies of different shapes.
