He is to be known as a ‘constant renunciate’, who does not desire or hate. O mighty-armed, the one given to nir-dvandvatā (freedom from dual responses) is comfortably freed from bondage.
Sannyāsa, says Krishna, is not a physical or bodily attribute. It is the sublime spiritual enrichment the mind is able to gain and preserve. The adornment is in the nature of inner sublimity and elegance, eliminating all desireful and hateful indulgences.
All dvandvas (pairs of opposites) are rooted in love and hate. Normally everyone goes on enhancing these during interactions and involvements. The number, intensity and frequency of love-hate indulgences only increase day by day. These only vitiate life and interactions; but this fact is not recognized and acted upon. Consequently the entanglements become stronger every day.
On the other hand, one who rises above dvandvas, gets liberated without courting inflicting disciplines and denials. It is a comfortable practice, resting on the mind and intelligence, with tangible effect every time. Even a little of this practice has great effect.
