But for the knowledge of the Self it is necessary to have the power of a complete intellectual passivity, the power of dismissing all thought, the power of the mind to think not at all which the Gita in one passage enjoins. This is a hard saying for the occidental mind to which thought is the highest thing and which will be apt to mistake the power of the mind not to think, its complete silence for the incapacity of thought. But this power of silence is a capacity and not an incapacity, a power and not a weakness. It is a profound and pregnant stillness. Only when the mind is thus entirely still, like clear, motionless and level water, in a perfect purity and peace of the whole being and the soul transcends thought, can the Self which exceeds and originates all activities and becomings, the Silence from which all words are born, the Absolute of which all relativities are partial reflections manifest itself in the pure essence of our being. In a complete silence only is the Silence heard; in a pure peace only is its Being revealed. Therefore to us the name of That is the Silence and the Peace.
