secretion many hundreds of these male cells ( the spermatozoa ) go inside the female uterus with the semen, Even inspite of the fact that there are similarly a great number of female cells present in the uterus, (the ova) only a few pairs combine to form the embryo-which form the complete seedlings of the child of humanity to be. It is said by the modern doctors that as soon as this combi nation of a spermatozoon and an ovum takes place and the embryo is formed, life creeps in and development begins to take place. This creeping in of the life is really the coming in of the Soul which only means life. This Soul, which comes in, can only be of that one whose Karmic body is such that at least more than fifty percent of the molecules constituting that body, must be similar to the molecular construction of the embryo. There may be so many of these embryons inside the uterus. Now only those embryons which correspond with more than 50 percent of the molecular construction of the female body ( of the mother) can remain in the uterus and the rest must get out. Most usually a single embryon remains finally and then it is said that conception has taken place. In some cases we find twins, triplets etc. too,
