The physical work for quiet is only helpful as it makes the body a better instrument for the mind and for the will.

A quiet body is of no use if it contains an unquiet mind which is going to pull it out of shape or start it up in agitation at the least provocation.

In such a case, the quiet body in its passive state is only a more responsive instrument to the mind that wants to raise a dust.

One--and the most helpful way of quieting the mind--is through a steady effort at concentration.

One can concentrate; on doing nothing--that is, on sitting quietly in a chair or lying quietly on the bed or the floor.
