Guarding

 On Thought Control and Guarding the Mind:

Commenting on the DHAMMAPADA verses regarding the volatility of human thought, the Mother emphasized that thoughts are actual forces we let into our consciousness, and we must learn to curate them like guests in a house:

"Nothing can harm you as much as your own thoughts unguarded."

The Mother says something like this-

We live in a world of vibrations, a world of waves... When you are in a state of passivity, all kinds of thoughts, suggestions, and impulses enter into you without your even being aware of it. You must learn to watch your mind, to be a sentinel at the door of your consciousness. When a thought approaches, you must look at it and say: 'Does this belong to the truth? Does this make me progress?' If it is a thought of weakness, of fear, of jealousy, or of anger, you must push it away immediately, as you would throw an enemy out of your house.
