I won't go into details as GIYF, but Zohar is purely speculating -- there's no actual science behind her claims (merely some sparse and rather questionable math, which AFAIK came only years after her book). Also, quantum vacuum is not absolute space-less emptiness, and of course, the question still remains, where did it come from? Her understanding of concepts such as Brahman, Tao, etc. is rather off, too. And lastly, transcendent and immanent god cannot be omnipresent thus also not omnipotent while also allowing free will. Which of course is OK, but then fuck such impotent and untrustworthy god.
