“Wisdom is the supreme part of happiness.”

"Fifth Talk in The Oak Grove, 11 June 1944" http://www.jkrishnamurti.org/krishnamurti-teachings/view-text.php?tid=173&chid=4529&w=%22To+understand+oneself+requires+patience%22&s=Text, J. Krishnamurti Online, JKO Serial No. 440611, Vol. III, p. 219
Posthumous publications, The Collected Works
Context: To understand oneself requires patience, tolerant awareness; the self is a book of many volumes which you cannot read in a day, but when once you begin to read, you must read every word, every sentence, every paragraph for in them are the intimations of the whole. The beginning of it is the ending of it. If you know how to read, supreme wisdom is to be found.

Variant: Life's great happiness is to be convinced we are loved.

Variant translations and selections:
Happy is the man that has found wisdom, and the man that gets discernment, for having it as gain is better than having silver as gain and having it as produce than gold itself. It is more precious than corals, and all other delights of yours cannot be made equal to it. Length of days is in its right hand; in its left hand there are riches and glory. Its ways are ways of pleasantness, and all its roadways are peace. It is a tree of life to those taking hold of it, and those keeping fast hold of it are to be called happy.
Proverbs 3:13-18; New World Translation http://www.watchtower.org/e/bible/pr/chapter_003.htm#bk13
Context: My son, despise not the chastening of the LORD; neither be weary of his correction: For whom the LORD loveth he correcteth; even as a father the son in whom he delighteth. Happy is the man that findeth wisdom, and the man that getteth understanding.
