' Hua Hu Ching '

68. In angelic dual cultivation, one learns to follow the
Tao.
To approach the Tao, you will need all your sincerity,
for it is elusive, first revealing itself in form and
image, then dissolving into subtle, indefinable
essence.

Through it is uncreated itself, it creates all things.
Because it has no substance, it can enter into where
there is no space.
Exercising by returning to itself, winning victories by
remaining gentle and yielding, it is softer than
anything, and therefore it overcomes everything
hard.

What does this tell you about the benefit of non-action
and silence ?
