“ But grief should be the instructor of the wise;        10Sorrow is knowledge: they who know the mostMust mourn the deepest o’er the fatal truth,The Tree of Knowledge is not that of Life” lord byron

I love thus quote because it makes a clear distinction betuween mere knowledge as percoeved by the mind, and wisdom or gnosis as oercoeved or experienced by the heart....the tree or the divine source in everything
