OP mentions the "womb of the celestial female" who birthed our spirits.
Orson Pratt, The Seer, Vol. 1, No. 7 (July 1853), 103
How many different laws these particles have acted under during the endless school of experience through which they have passed is not known to us. What degree of knowledge they have obtained by experience, previous to their organization in the womb of the celestial female, is not revealed. One thing is certain, the particles that enter into the organization of the infant spirit, are placed in a new sphere of action: the laws to govern them in this new and superior condition must be different from any laws under which they had previously acted.
