Once, Darkness (personified form) goes to the royal Court of Lord Vishnu to complain that Sun had been causing him immense trouble and harassment chasing him out. Lord Vishnu called for the Sun and asked it to speak in its own defense. Sun said that it was unaware of any such problem. Sun asked Lord Vishnu to call for Darkness as the former had not seen the complainant at all. But it was impossible for Darkness to come to the Court in the presence of the Sun. Darkness is no phenomenon by itself, absence of light is darkness.
