There are, however, various disagreements here among all the author-sages. Learn of these too as they are spoken: ‘The head is formed first in the womb,’ considers Kumāraśiras Bharadvāja, on the grounds that it is the seat of all the sense organs. ‘The heart,’ says Kāṅkāyana, the physician of Bāhlīka, because of its being the substratum of consciousness. ‘The navel,’ says Bhadrakāpya, on the grounds that it is the source of food. ‘The large intestine and rectum,’ says Bhadraśaunaka, on the grounds of their being the seat of wind. ‘The hands and feet,’ says Baḍiśa, because they are the instruments of man. ‘The sense organs,’ says Janaka of Videha, on the grounds that they are his seats of intellect. ‘It is imperceptible, hence inconceivable,’ says Mārīci Kaśyapa. ‘The formation of all limbs occurs simultaneously,’ says Dhanvantari; and that is reasonable, because of the simultaneous formation of all limbs, such as the heart and the rest.”
