This is said to be the second mode of birth and is inferior. Those living creatures which take birth after the lapse of sometime, bursting through the earth, are said to be germ-born beings, O foremost of twice-bom persons! Creatures of two fect or of many fect, and those which move crookedly, are the beings born of wombs. Among them are some which are deformed, you best of men! The eternal womb of Brahma should be known to be of two kinds, viz., penance and meritorious acts. Such is the doctrine of the learned. Action should be understood to be of various kinds, such as sacrifice, gifts made at sacrifices, and the meritorious duty of study for every one that is born; such is the teaching of the ancients. He who duly understands this, comes to be considered as possessed of Yoga, you chief of twice-born persons.
