This Master did not merely reach a very old age, but did so in spite of being nearly beaten to death by the Communists. Cannot recall the exact year, but he was well over 100 when the commies began to beat him more than one time (maybe 3?), while he was in prison. Each time he was left for dead but recovered.
jeeprs: Great interview with the Master, who clears up, as a Master does, the 'difference' between other-power & self-power or Pure Land & Chan.
“Why insist so much on this difference?” [Master Hsu Yun] asked. “You know that in reality there is nought but the One Mind. You may choose to regard it as in you or out of you, but “in” and “out” have no ultimate significance whatever – just as you, Mr P’u, and I and Amida Buddha have no real separateness. In ordinary life, self is self and other is other; in reality they are the same.
Only consider helping others and forget yourself. Master Hsuan Hua
