Thought Adjuster indwelling and fusion as the goal of mortal life (UB 108-111) = Tibetan concept of Buddha-nature (Tathagatagarbha) and the subtle body

Tibetan Buddhism teaches that every sentient being possesses the Buddha-nature, an indwelling seed of enlightenment identical in essence with the Dharmakaya (the absolute reality), and that liberation consists in realizing this indwelling nature. This is structurally the same as the UB teaching of the Thought Adjuster: a divine fragment actually indwelling the mortal mind, identical in nature with the Universal Father, whose fusion with the mortal is the goal of the ascending career. The UB's explicit comparison of the Adjuster with the Hindu Atman (111:0.4) extends naturally to the Buddhist Tathagatagarbha, which is the Mahayana Buddhist refinement of the same Upanishadic concept.
