Premanand Maharaj Ji
How do I stop grieving over something that has already happened, like a loss?
Let go of grief for what is past
Grieving over what has passed is a great foolishness, a mistake, because it has already passed. Have a little patience. Leave what is behind, and rest in the Lord, who is mangal bhavan, the home of all good, and the remover of harm.
To grieve over what has already passed is a great folly, a mistake. It has gone by. Why grieve for it? What was to happen has happened.
