13.81

外論曰。聖人應迹異彼凡夫。或乘龍象以處胎。乍開脇腋而出世。雖復無關兩氣非假二親。至於左右之殊。其優劣之異一也。

The Outsiders' treatise says: The response traces of sages are different from ordinary mortals: either they mount a dragon or elephant to dwell in the womb, or they suddenly open the ribs and armpit to emerge into the world. Although this is equally unrelated to the two breaths and does not depend on two parents, when it comes to the distinction between left and right, their difference in superiority and inferiority is the first point.
