Prahlāda Mahārāja, the most dear servitor of the Supreme Personality of Godhead, once went out touring the universe with some of his confidential associates just to study the nature of saintly persons. Thus he arrived at the bank of the Kāverī, where there was a mountain known as Sahya. There he found a great saintly person who was lying on the ground, covered with dirt and dust, but who was deeply spiritually advanced.
