Nature gave us a sense of humor in order to transcend and criticize ourselves, and laugh at what nature does to us.
A sense of humor lets us see ourselves from a higher degree, and thus can also help elevate us outside of our current degree to a higher one. Viewing and laughing at ourselves from aside can spark an inner scrutiny into who we truly are, and whether we can be more than what we currently are.
Kabbalists not only laugh at themselves but also constantly criticize who and what they are, and how they can change. If we know how to laugh at ourselves, then as it is written, “God has brought me laughter” (Genesis 21:6) from which we can grow.
I personally like jokes about human weaknesses and how we can rise above them. Such jokes help us develop, because if we know that we have such negative qualities, then we can work on rising above them.
Everything has been created for our development, including a sense of humor. A sense of humor gives us the strength and the ability to develop.
On the other hand, we should never make fun of others. We should laugh only about qualities that exist generally in humanity, as by so doing, we can highlight weak spots that we can change in ourselves, and as such progress to more and more balance and harmony among each other and with nature.
