Acceptance

When we don't accept an undesired event it becomes anger

When we accept it, it becomes tolerance.

When we don't accept uncertainty, it become fear

when we accept it, it becomes adventure.

When we don't accept other's bad behavior towards us,

It becomes hatred

When we accept it, it becomes forgiveness.

When we don't accept other's success, it become jealousy

When we accept it, it becomes inspiration.

Acceptance is the key to handling life well.

In the Bhagavad-gita it's called surrender.
