When does the spirit enter the body?

[Bat]

The orange-ray body is the physical body complex. This body complex is still not the body you inhabit but rather the body formed without self-awareness, the body in the womb before the spirit/mind complex enters. This body may live without the inhabitation of the mind and spirit complexes. However, it seldom does so.

I am assuming that the 3rd Density body, of Mind/Body/Spirit incarnates at the very last moment of the Birth process to lessen complications. I am not sure if i read that in the Law of One or just thought it as a vivid memory.

Hope that helps a little.
