"Tere liye main le loon, dunya se beir, piya."

"Beir" meaning Inimicalness.

And, from the internet we find:
Hostility (also called inimicality) is a form of angry internal rejection or denial in psychology.

I really like the version where Devdaas decides to stay with Chandramukhi, rather than shriveling up and dying outside of Paro's door.

Does that make sense?
