Om Swami
Why does attachment keep me in sorrow even when the thing I am attached to is good?
Attachment keeps the door to sorrow open
Whether the thing is right or wrong, any attachment leaves a door to sorrow open. The end of attachment is moksha (liberation).
The end of attachment is liberation. Whether the thing is right or wrong, as long as there is attachment to anything, a door to sorrow and disappointment stays open forever.
