Mbh 12.332.1c

[1775] Upon the dissolution of the body, another body, which is as much destructible as the one that is destroyed, is kept ready for the burnt and destroyed creature (to migrate into) even as one boat goes to another for transferring to itself the passengers of the other.[1776] In consequence of an act of congress, a drop of the vital seed, that is inanimate, is cast into the womb. I ask thee, through whose or what care is the embryo kept alive? That part of the body into which the food that is eaten goes and where it is digested, is the place where the embryo resides, but it is not digested there. In the womb, amid urine and faeces, one's sojourn is regulated by Nature. In the matter of residence therein or escape therefrom, the born creature is not a free agent. In fact, in these respects, he is perfectly helpless. Some embryos fall from the womb (in an undeveloped state). Some come out alive (and continue to live). While as regards some, they meet with destruction in the womb, after being quickened with life, in consequence of some other bodies being ready for them (through the nature of their acts).[1777] That man who, in an act of sexual congress, injects the vital fluid, obtains from it a son or daughter. The offspring thus obtained, when the time comes, takes part in a similar act of congress. When the allotted period of a person's life is at its close, the five primal elements of his body attain to the seventh and the ninth stages and then cease to be. The person, however, undergoes no change.[1778] Without doubt, when persons are afflicted by diseases as little animals assailed by hunters, they then lose the powers of rising up and moving about. If when men are afflicted by diseases, they wish to spend even vast wealth, physicians with their best efforts fail to alleviate their pain.
