Since the Supreme Personality of Godhead is ever existing, all-blissful and full of knowledge, His different energies are also ever existing in the dormant stage. Thus when the mahat-tattva was created, it manifested the material ego and swallowed up the darkness which covered the cosmic manifestation at the time of dissolution. This idea can be further explained. A person at night remains inactive, covered by the darkness of night, but when he is awakened in the morning, the covering of night, or the forgetfulness of the sleeping state, disappears. Similarly, when the mahat-tattva appears after the night of dissolution, the effulgence is manifested to exhibit the variegatedness of this material world.
