...my opinion is that we have, in the person of Da Free John, a Spiritual Master and religious genius of the ultimate degree. I assure you I do not mean that lightly. I am not tossing out high-powered phrases to 'hype' the works of Da Free John. I am simply offering to you my own considered opinion: Da Free John's teaching is, I believe, unsurpassed by that of any other spiritual Hero, of any period, of any place, of any time, of any persuasion.
Ken Wilber, 1980, Foreword to Scientific Proof of the Existence of God Will Soon Be Announced by the White House! by Da Free John (Adi Da; online copy from unofficial Adidam advocacy site)
I participated in and observed the evolution of one of the most exciting and sobering sacred experiments ever made....No matter what Adi Da tried, he couldn’t get people to realize the Divine Self on his terms, surrendering eternally to him as guru. He never really wanted us to duplicate his radical independence and creative originality in life.Adi Da
It is obvious, from all sorts of subtle details, that he knows what IT's all about ... a rare being.Adi Da
In the meantime, I affirm all of the extremes of my statements about Da: he is one of the greatest spiritual Realizers of all time, in my opinion, and yet other aspects of his personality lag far behind those extraordinary heights. By all means look to him for utterly profound revelations, unequalled in many ways; yet step into his community at your own risk.Adi Da
