Changes

It depends on the state of development of the soul which wants to reincarnate―we take the word "soul" here in the sense of the psychic being, what we call the psychic being―it depends on its state of development, on the milieu in which it is going to incarnate, on the mission it has to fulfil―that makes many different conditions.... It depends very largely on the state of consciousness of the parents. For it goes without saying that there is a stupendous difference between conceiving a child deliberately, with a conscious aspiration, a call to the invisible world and a spiritual ardour, and conceiving a child by accident and without intending to have it, and sometimes even without wanting it at all. I don't say that in the latter case there cannot also be an incarnation, but it usually takes place later, not at the conception. <ref>http://incarnateword.in/cwm/08/24-october-1956#p17</ref>
