Mother, how can one prevent the mind from intervening?
Ah! First you must will it, and then you must say, as to people who make a lot of noise, “Keep quiet, be quiet, be quiet!”; you must do this when the mind comes along with all its suggestions and all its movements. You must tranquillise it, pacify it, make it silent. The first thing is not to listen to it. Most of the time, as soon as all these come, all these thoughts, one looks, seeks to understand, one listens; then naturally that imbecile believes that you are very much interested: it increases its activity. You must not listen, must not pay attention. If it makes too much noise, you must tell it: “Be still! Now then, silence, keep quiet!” without making a lot of noise yourself, you understand? You must not imitate those people who begin shouting: “Keep quiet”, and make such a noise themselves that they are even noisier than the others!
