He was a close friend of Christmas " Toby" Humphrys founder of the Buddhist Society of London..
He ( Gray ) lived in Monaco and maintained his own vineyard just over the border in Provence.
Following an introduction via Toby, Peter and I ( who were newly married ) went to visit him and came back with several bottles of his own best vintage...he was by then quite elderly.
He WAS an interesting man..His view of Rebirth was almost identical to that of Ajahn Buddhadhat ( Buddhadasa ) i.e. that there was frequently a basic misunderstanding of the concept due to the tendency to see time as linear. I had just returned from Bangkok and had been to talks by Buddhdasa. ( I at the time had a job with the British Council straight after leaving Oxford. )
When this was pointed out to him he was very interested but clearly had no knowledge of Buddhadasa's writings.
He had arrived at similar conclusions independantly.
The going for refuge is the door of entrance to the teachings of the Buddha.
