Krishna is the sun that enables us to see ourselves
The devotees of the Lord can see everything in true perspective due to the light disseminated by Lord Krishna. By the grace of the Lord the pure devotee cannot be in the darkness of ignorance. Therefore, it is necessary that we must always be in the sight of Lord Krishna so that we can see both ourselves and the Lord with His different energies. As we cannot see anything in the absence of the sun, so also we cannot see anything including our own self, without the factual presence of the Lord. Without Him all our knowledge is covered by illusion.
