"Thinking, or more precisely identification with thinking, gives rise to and maintains the ego, which, in our Western society in particular, is out of control. It believes it is real and tries hard to maintain its supremacy. Negative states of mind, such as anger, resentment, fear, envy, and jealousy, are products of the ego."
The quote is from a goy, but I believe Rebbe Nachman and the Baalei Mussar would agree.
So that would be a GREAT avoda for today [and the rest of our lives].
Let go of your ego. It causes you and those around you a lot of trouble.
How do you do it?
For that we have holy books to guide us.
