釋淨土群疑論 2.27

2.27

Answer: This is also known by deduction from the principles. In the defiled land, the intermediate state of those being born into heaven travels with feet below and head above; the intermediate state of hell travels with head below and feet above; humans, ghosts, and animals travel with their bodies horizontal, like birds flying. Now, when being born in the pure land, feet are below and head is above. The passage in this sūtra, 'sitting inside the lotus flower,' is precisely its appearance. Another explanation says there is a difference: the intermediate state of those being born into heaven has feet below and head above, proceeding standing up to receive birth; the pure land intermediate state proceeds seated to receive birth.
