In the story of Kayin and Hevel we come to hear to what jealousy and envy can lead.
The Hebrew phrase tikkun olam (pronounced tee-KOON oh-LUHM) means "world repair." In modern Jewish circles, tikkun olam has become synonymous with the notion of social action and the pursuit of social justice. Created in the image of God each human being is requested to come close to the Bo're and to be a partaker of a marvellous peaceful world to which each member has to contribute out of free will. In order for the balance between good and evil intended by God to be restored, humans must be involved in the world's reparation and can not keep aside or aloof or 'do nothing' to get social justice or a better world.
Created in the image of God man has 49 sefirot in him or a 49-step process of self-refinement, having received orders from his Maker Who expect to fit man in His holy Plan.
