What helps enormously in our attempts to know our own minds is, surprisingly, the presence of another mind. For all the glamour of the solitary seer, thinking usually happens best in tandem.

It is the application of a light pressure from outside us that firms up the jumbled impressions within. The requirement to verbalize our intimations mobilizes our flabby reserves of concentration.
