Random Watts

The simplest cure is to feel free to block
so that one does not block at blocking. When one feels
free to block, the blocking automatically eliminates
itself [and then action -- or nonaction -- arises
spontaneously]....The principle here is, of course, the
same as getting out of the contradiction of 'trying to
be spontaneous' through accepting the 'trying' as
'spontaneous' [in and of itself]...." -- Watts. The Way of Zen
