It leaves no time for the silence, the withdrawal, the quiet attention to the spiritual, which is essential if it is to develop all its powers.

Yet the literature of the Spirit is full of warnings on this subject.
_Taste_ and see that the Lord is sweet.

They that wait upon the Lord shall renew their _strength_.

In quietness and confidence shall be your _strength_.

These are practical statements; addressed, not to specialists but to ordinary men and women, with a normal psycho-physical make-up.
