yogair hemeva durvarnam

nirvairadibhir atmanam
yac-chilam anuvartitum
yogaih—by the rectifying processes; hema—gold; iva—like; durvarnam—inferior quality; bhavayisyanti—will purify; sadhavah—saintly persons; nirvaira-adibhih—by practice of freedom from animosity, etc.; atmanam—the self; yat—whose; silam—character; anuvartitum—to follow in the footsteps.
In order to follow in his footsteps, saintly persons will try to emulate his character by practicing freedom from animosity, just as the purifying processes rectify gold of inferior quality.
Yoga practice, the process of purifying oneís existential identity, is based mainly on self-control. Without self-control one cannot practice freedom from animosity. In the conditional state, every living being is envious of another living being, but in the liberated state there is an absence of animosity. Prahlada Maharaja was tortured by his father in so many ways, yet after the death of his father he prayed for his fatherís liberation by the Supreme Personality of Godhead. He did not ask any benediction that he might have asked, but he prayed that his atheistic father might be liberated. He never cursed any of the persons who engaged in torturing him at the instigation of his father.
