Spirituality: Chassidic Wisdom

Chassidic wisdom teaches that:
"we should all live as if we carry two pieces of paper, one in each
pocket. On one paper should be written, "I am nothing but ashes and
dust," and on the other, "The whole world was created for me." Both of
these sayings are correct. The key to true happiness is to master the
understanding of when to pull out which paper."
