Cosmic repair refers to the mystical concept in Jewish thought where the act of repairing the world (Tikkun Olam) is seen as a way to restore harmony and balance to the cosmos. This idea emphasizes that human actions, particularly through prayer, observance of commandments, and ethical living, can mend spiritual fractures that occurred during the creation process, known as the Shevirat HaKelim or 'breaking of the vessels'. This concept is central to Jewish mysticism, especially within Kabbalistic teachings, which explore the relationship between humanity and the divine.
