Bhagavad Gita, Chapter 11, Verse 55

He who does work for Me alone and has Me for his goal, is devoted to Me, is freed from attachment, and bears enmity towards no creature, he enters into Me, O Pândava.

The chapter closes with a real, practical list, not abstract praise but things a person can actually live out.

Working for that purpose, staying free of attachment, and holding no ill will toward anyone are named as the real, visible marks of this devotion. What started as an overwhelming vision ends with something entirely down to earth.
