Yajnavalkya Upanishad: (Sanskrit) A metrical rendering of the Jabala Upanishad, which expounds on sannyasa, renunciation of worldly life in the quest for liberation.
Yukta-vairagya - appropriate renunciation; renunciation which is suitable for entrance into bhakti. This is defined in Bhakti-rasamrtasindhu (1.2.255): "When one is detached from material sense enjoyment, but accepts in appropriate proportion objects which are favorable to one’s bhakti, and shows special inclination toward things which are directly related to Krsna, such as mahaprasada, his renunciation is known as yukta-vairagya.” (See phalgu-vairagya with which this is contrasted.)
A renunciate spiritual seeker, usually seen in India. Saddhus have no possessions having given up everything in the material world in search of personal spiritual growth. The ultimate goal of which is Enlightenment.
