From Sanskrit, apara means “relative” and vairagya means "without-passion" or "dispassionate" - the word itself implies an ascetic disinterest in the things that others would normally be attached to. The name, vairagika, is given to a yogi who has renounced all their worldly passions and desires for a state of vairagya.
Vairagya comes naturally through gradually developing a desire for inner fulfillment and spiritual practice in which attachments to worldly objects fall away. Thus, there is no need to suppress or become averse to desires for things in the material world.
The true state of apara vairagya is an inner state, rather than an external lifestyle. It can be practiced equally by those with families and careers, as well as those who have renounced the material world. Practicing apara vairagya helps concentration and fuels the desire for spiritual enlightenment.
