One who wants to be free of material entanglement should take to the service of the Supreme Personality of Godhead and give up the contamination of ignorance, involving pious and impious activities. Thus one regains his original identity, just as a block of gold or silver sheds all dirt and becomes purified when treated with fire. May that inexhaustible Supreme Personality of Godhead become our spiritual master, for He is the original spiritual master of all other spiritual masters.
