The cure for depression is joy in discovering the reason for everything that happens to us, the source of all life. Negative emotions overwhelm us because of the egoistic nature to enjoy that led us to the construction of a hostile and evil world. Today, no one is satisfied and negative feelings are intensifying. The negative emotions awaken in us so that we will change by building a good environment in which we will feel and fulfill what is good for others. The system of nature gives us negative feelings so that we can balance them with positive relationships. The wisdom of Kabbalah teaches us how to create relationships that accord to the system of nature.
