Don’t Engage with Negativity
Negativity is a disease condition.
If negative thoughts come from the ego mind, refuse to hold them or reason with them. Simply release them, focus and re-center on the present moment.
Negativity that is perceived to come from the outside world is harder.
Let the negative pass and see God in the person or circumstance. View them with a loving heart and wait for that small voice of the divine that shows the right next action.
