amuñcan mukhato ruṣā
mahīṁ nirvīrudhaṁ kartuṁ
In this verse Vidura is addressed as rājan, which means “O King.” In this regard, Śrīla Viśvanātha Cakravartī Ṭhākura comments that a dhīra never becomes angry because he is always situated in devotional service. Advanced devotees can control their senses; therefore a devotee can be addressed as rājan. A king controls and rules in various ways among citizens; similarly, one who can control his senses is the king of his senses. He is a svāmī or gosvāmī. The svāmīs and gosvāmīs are therefore sometimes addressed as mahārāja, or king.
