How did my soul come into existence?

If it is true that the soul has had a previous existence in some other form before its connection with the body, why is it that it has no distinctive recollection of that existence?

The soul existed in embryo before it was projected into the external world—before it was made apparent as an individual, according to the laws of time. 

And yet the soul through its human organism has no memory of that prior existence. 

It can remember back to the days of childhood, but it can go no farther. There seems to be a power, governing the attribute of memory, that is dependent on form and its conditions. 

Memory expresses itself through form. 

It turns to the past through form and it stretches its clairvoyant vision from the past to the future through form—it is dependent on the laws of form to a very great extent. 

Therefore, it is that you do not remember, having had a prior existence to the one, which is now your own, so-called, as an individual. 

I have no recollection of an existence prior to the existence of my earthly life, yet I have listened to many who declared that they have a distinct recollection of scenes far, far back in the past, dating long before their earth lives.

—Professor John Hubbard in Spirit
