So many enlightened people have quoted this as the one thing that matters most than anything else.
I read this article "This column will change your life"[1] about an Indian philosopher named Jiddu Krishnamurti many many years ago but this passage really stuck with me:
Krishnamurti went on to give countless talks at which he frequently implied that his audience shouldn't be wasting their time listening to spiritual talks. But perhaps the most striking was a 1977 lecture in California.
"Part-way through this particular talk," writes Jim Dreaver, who was present, "Krishnamurti suddenly paused, leaned forward and said, almost conspiratorially, 'Do you want to know what my secret is?' " (There are several accounts of this event; details vary.) Krishnamurti rarely spoke in such personal terms, and the audience was electrified, Dreaver recalls. "Almost as though we were one body we sat up… I could see people all around me lean forward, their ears straining and their mouths slowly opening in hushed anticipation."
Then Krishnamurti, "in a soft, almost shy voice", said: "You see, I don't mind what happens."
