…There is always a way of isolating oneself by an atmosphere of protection, if one knows how to have an extremely quiet vibration, so quiet that it makes almost a kind of wall around you. But all the time, all the time one is vibrating in response to vibrations which come from outside. If you become aware of this, all the time there is something which does this (gesture), like this, like this, like this (gestures), which responds to all the vibrations coming from outside.
You are never in an absolutely quiet atmosphere which emanates from you, that is, which comes from inside outward (not something which comes from outside within), something which is like an envelope around you, very quiet, like this—and you can go anywhere at all and these vibrations which come from outside do not begin to do this (gesture) around your atmosphere.
