Verse
तस्मादसक्तः सततं कार्यं कर्म समाचर ।असक्तो ह्याचरन्कर्म परमाप्नोति पूरुषः ॥
Therefore without attachment perform ever the work that is to be done (done for the sake of the world, lokasangraha, as is made clear immediately afterward); for by doing work without attachment man attains to the highest.
Gītā 3·19
