The form is built by Nature, the soul is the Divine element that enters it as a guest enters its house. Generally this entry does not happen while the foetus is being formed. Usually it is a few years before the soul adopts the mind and body that are in a state of formation, attracted towards it by the light of an intuitive sense of the experience it needs. In most instances the first contact takes place around 7 or 10 years and if often marked by an upsurge of certain unusual feelings and thoughts, or even experiences that go into the background as one enters adolescence and the onrush of vital forces and mental questioning throws everything topsy turvy. But in those marked for a spiritual life the first contact is renewed as we sail past adolescence giving birth to a conscious aspiration. That’s when we can say that the soul has truly identified with the body just as the householder grows one with the house and makes it his ground or nest for further experiences. On the other hand, in some cases, perhaps many, it hardly links itself with the body though it does draw its share of experiences through it for growth. Such people who are perhaps the majority are often devoid of any true faith though they may subscribe to a fixed and formal religion and practice it, have no higher aspiration or idealism, and are content with material comforts and vital pleasures which they pursue as their goal just as a vulture pursues dying flesh.
As to transmission straight from the adult or old body to another without the process of death, it is very much possible and has been done. It requires a considerable degree of inner development but the question is which body will it transit to? A body not much in contact with the soul is like a haunted house and not worthy of being occupied by the celestial guest. And a body that is already being used by a soul for its growth cannot be just force occupied. What does however happen sometimes is that a developed being or a god occupies, seizes, posseses the soul and body of another developing soul and uses it for its purposes.
What will however happen one day is that through the confluence of a higher science and spiritual power a very developed soul will be able to create a living body for itself using the occult processes of Nature and her arrangement of elements. Then the soul can just leave one body consciously as a worn out robe and enter the consciously formed body without passing through death. This is one of the things in the offing.
Affectionately,
