No one can help us to achieve the intimate isolation by which we find our secret worlds, so mysterious, rich and full. If others intervene, it is destroyed. This degree of thought, which we attain by freeing ourselves from the external world, must be fed by the inner spirit, and our surroundings cannot influence us in any way other than to leave us in peace.

It seems a strange thing to say, but this can happen even if the child merely becomes aware of being watched. After all, we too sometimes feel unable to go on working if someone comes to see what we are doing. The great principle which brings success to the teacher is this: as soon as concentration has begun, act as if the child does not exist. Naturally, one can see what he is doing with a quick glance, but without his being aware of it.
