Bageshwar Dham Sarkar
Why does attachment (moh) cause sorrow, and how can I be free of it?
Attachment is the sorrow
Sorrow and joy come from calling someone your own, so moh itself is dukh and freedom from it is sukh. Saying this is easy and living it is hard, and that is why coming to satsang is necessary.
Whoever you become attached to, you will feel sorrow and happiness in every little thing of theirs.
