Root out the conception of duality by the conception of the absolute unity. Destroy the Bheda Buddhi or the intellect that creates differences, distinctions and separateness. You can now enjoy the eternal bliss of the non-dual Self. You are a Jivanmukta now. One Atman appears to be many, as one sun appears to be many in various pots of water.
Many suns are false.
They are mere reflections only. So also the many Jivas are illusory. The one sun alone is real. Even so One Brahman alone is real. The divine life that throbs in every atom of the universe dwells also in the hearts of human beings.
