वैराग्य
Vairagya is dispassion — freedom of the heart from attachment and aversion toward the non-self — a cornerstone of Indian spiritual discipline (the 'jnana-vairagya' pair is famous in Vedanta). In the processed verses bhakti-yoga applied to Vasudeva begets it swiftly and causelessly: 'janayaty asu vairagyam' (SB 1.2.7).
