It is not, as so many people assume it to be, a process of “thinking things over.” Rather, it is making the mind completely receptive to reality. It is stilling the thought-processes–those restless ripples that bob on the surface of the mind–so that truth, like the moon, may be clearly reflected there. It is listening to God, to Universal Reality, for a change, instead of doing all the talking and “computing” oneself.
