Alaya-vijnana is the basic source of life. As it comes into contact with different conditions and circumstances, it gives rise to various mental formations and actions, hence karma. The seeds of karma are [in turn] stored in this giant warehouse of alaya-vijnana. The relative abundance of the good or bad karma in this giant warehouse then determines the direction of the next rebirth. When a being dies, the alaya-vijnana is the last to leave the physical body. When a being is reborn, the alaya-vijnana is the first to arrive in the next body. It is the core of rebirth.
