“Although Dhruva Maharaja was only a five-year-old boy, he underwent severe austerities by eating simply dry foliage, drinking only water and taking no food. In this way, after six months, he was able to see the Supreme Personality of Godhead face to face. When he saw the Lord, he forgot all his austerities and said, svamin kritartho'smi: ‘My dear Lord, I am very pleased.’” (Shrila Prabhupada, Shrimad Bhagavatam, 4.30.4 Purport)
