what is a heavenly pact in jjk

In the anime and manga series Jujutsu Kaisen, a Heavenly Pact, also known as a Heavenly Restriction, is a binding placed on a sorcerers body at birth. These bindings usually refer to limitations on the human body, such as trading off physical capability for cursed energy potential or vice versa. Heavenly Pacts provide both rewards and risks to the sorcerers who make them, like a high-stakes game of magical roulette. The more power a Heavenly Pact gives, the more it takes, and the user must be careful not to overuse their abilities. Each person has a Heavenly Pact as a reason for their unique abilities. For example, Maki doesn't have access to curse energy due to a Heavenly Pact, but she has incredible physical abilities to the point she should be a G2 sorcerer.
