"In the sixties and seventies, he presided over the wave of hippyism that swept Amsterdam. He pioneered the reinstating of poetry as a performing art, and was all over the place in New Age publications almost until his dying breath, displaying in passing his considerable erudition in religion and philosophy. Not being much of a reader, I never read his poetry though I attended some of his performances, and had one conversation with him after his show in my hometown Leuven, ca. 1980."
