One should learn how to associate with the devotees of the Lord by gathering with them to chant the glories of the Lord. This process is most purifying. As devotees thus develop their loving friendship, they feel mutual happiness and satisfaction and by thus encouraging one another they are able to give up material sense grantification, which is the cause of all suffering. — Srimad Bhagavatam, 11.03.30.
The Supersoul, the Supreme Personality of Godhead, is the source of light.
Bhagavad Gita 13.18,
Without being self-controlled, without being disciplined and without being fully obedient, no one can become successful in following the instruction of the spiritual master and without doing so, no one is able to go back to Godhead. — Srimad Bhagavatam, 01.05.24.
God is bigger than the biggest and smaller than the smallest. That is His greatness.
