I am trying hard to understand your belief. According to you (correct me if I understand you wrong)
1) Universal mind is impersonal (no free will), absolute and timeless (no begining and end)
2) Everything in this universe are manifestations of this Mind
3) Some of the manifestations are transient and personal (having free will), like ego and illusion.
Now comes my comment: 1) and 3) are contradictory to each other: how and when does this impersonal mind with no free produce part of himself as personal (having free will) and time bounded ego and illusion? An impersonal fore doesn't know how to make a decision, because making decision requires a free will.
