How does the spirit enter the body? What determines what body you get?
The soul, say, it that comes into a human body is contained in the sperm of the father. So, the mother produces “the seed”, if you will, for the body and the father produces the life that enters that. And according to our activities and desires in our past life, we will be placed in a particular body. It’s a big story but it’s all very scientifically orchestrated by the Supreme Lord. There’s an exact system in place that’s working. So, this is all the part of the knowledge we receive from the science of bhakti yoga.
