When the soul thus rises above the three gunas born of the embodiment in Nature, he is freed from subjection to birth and death and their concomitants, decay, old age and suffering, and enjoys in the end the Immortality of its self-existence.
Gītā 14·20Immortality is that supreme status in which the Spirit knows itself to be superior to death and birth, not conditioned by the nature of its manifestation, infinite, imperishable, immutably eternal,—immortal, because never being born it never dies…. But to arrive here at this greater spiritual immortality the embodied soul must cease to live according to the law of the lower nature; it must put on the law of the Divine’s supreme way of existence which is in fact the real law of its own eternal essence. In the spiritual evolution of its becoming, no less than in its secret original being, it must grow into the likeness of the Divine.
