You exist in the beginning, middle and end of everything, from the most minute particle of the cosmic manifestation—the atom—to the gigantic universes and total material energy. Nonetheless, You are eternal, having no beginning, end or middle. You are perceived to exist in these three phases, and thus You are permanent. When the cosmic manifestation does not exist, You exist as the original potency.
