Learn to ignore the mind's chatter
The greatest art is to ignore the mind. Not every thought or feeling that comes in the mind is speaking the truth. Abhyasa (practice) and vairagya (detachment) have to be adopted.
Somewhere, the root of meditation is exactly this: not every thought or feeling that arises in the mind is necessarily speaking the truth.
