Everything that intrudes upon the mental stillness in this highly critical stage must be rejected, no matter how virtuous or how "spiritual" a face it puts on. Only by the lapse of all thought, by the loss of all thinking capacity can he maintain this rigid stillness as it should be maintained. It is here alone that the last great battle will be fought and that the first great fulfilment will be achieved. That battle will be the one which will give the final deathblow to the ego; that fulfilment will be the union with his Overself after the ego's death. Both the battle and the fulfilment must take place within the stillness; they must not be a merely intellectual matter of thought alone nor a merely emotional matter of feeling alone. Here in the stillness both thought and emotion must die and the ego will then lose their powerful support. Therefore here alone is it possible to tackle the ego with any possibility of victory.
