I was reading, and I learned something new.

The bhajan is a traditional Hindu devotional song.

Most were written between the fourteenth and seventeenth centuries as a result of the Bhakti revivalist movement.

This movement's center was the idea that to attain spiritual salvation a person had only to attain a pure and selfless love of God.

For some interesting discussion, see Franny and Zooey by J.D. Salinger, and Deuteronomy 6:4-9.
