Mental Silence

This is something very well known in yoga. The simple fact of observing the victory one has gained – observing it mentally, you see, thinking about it – is enough to destroy the effect of the yoga which may have existed for years. A mental silence strong enough to prevent all outer vibrations from coming in, is indispensable. Well, that is something so difficult to achieve that one must really have passed from what Sri Aurobindo calls “the lower hemisphere” to the higher, exclusively spiritual hemisphere, for it not to happen.
