Through his past works he shall return once more to birth, entering whatever form his heart is set on. This mighty soul unborn grows not old, nor dies, for the soul is immortal and fearless. - Brihadaranyaka Upanishad
Your soul is an immortal body of light. It’s Absolute and super conscious essence is identical with God. Yet, this identity needs to be realized and unfolded within the soul. Toward this goal your soul undertakes many, many lifetimes in a physical body. You are now the sum total of all your past lives. You undergo every conceivable human experience as the forces of the body, ego and desire manifest.
In the latter lives the forces are transmuted toward spirituality. Finally, your soul realizes God. After resolving all residual karmas, your soul no longer incarnates into human form. As the Agamas and Vedas teach, the soul continues its evolution in the inner worlds. Therefore, you live joyously, strive for spiritual unfoldment and do not fear death.
