Om Swami
How do I let go of greed, anger and desire so I can be happy?
Rise above greed, don't serve it
The verse says to give up kama (desire), krodh (anger), lobh (greed) and moh (attachment). Do not become the servant of your vices. Someone who has everything and still cannot be happy is already in hell.
So learn to let go of your vices, learn to rise above your vices, and do not become the servant of your vices.
