SOME QUOTES ON EXPERIENCE:
Most of the quotes found on the net take its meaning of becoming an expert at something or learning something. Gurumayi expresses it in a different sense of "trying thoroughly". Here are some of them which I thought related to what she has said.

"One aspect of an experience that can make it surprising and amazing is that of confronting one's beliefs"

"Experience is not what happens to you. It is what you do with what happens to you."
Aldous Huxley

"Experience is that marvelous thing that enables you to recognize a mistake when you make it again."
Franklin P. Jones

"The immense merit of language was that it made possible the transmission of experience"
Bertand Russell
