The Turning About stage

Entering upon the eighth stage, with the turning-about at the deepest seat of consciousness, the Bodhisattva will become conscious that he has received the second kind of Transcendental- body (Manomayakaya) . The transition from mortal-body to Transcendental- body has nothing to do with mortal death, for the old body continues to function and the old mind serves the needs of the old body, but now it is free from the control of mortal mind. There has been an inconceivable transformation- death (acintya-parinama- cyuti) by which the false-imagination of his particularised individual personality has been transcended by a realisation of his oneness with the universalised mind of Tathagatahood, from which realisation there will be no recession.

With that realisation he finds himself amply endowed with all the Tathagata's powers, psychic faculties, and self-mastery, and, just as the good earth is the support of all beings in the world of desire (karmadhatu) , so the Tathagatas become the support of all beings in the Transcendental World of No-form. ~ Lankavatara sutra
