A question for you before we get started: Why do you think it was decided that all people would be born lacking the tool of spiritual perception?

So it would not be used to receive in order to receive?

To develop through our own efforts the capacity to attract the Light.

If we were born with such an understanding we would not be able to make an independent choice and therefore would be simply using our egoism, and therefore would never able to achieve equivalence of form with the Creator.

In order to experience the corporeal temporary desires and pleasures that would lead to a lack of fulfillment thus causing us to seek more permanent and desirable pleasures that would be a continuous flow of the light from the Ein Sof.

In order to develop it from the free will. All other sense have been there since the begging and this one we must attain.
