"When the deep meaning of things is not understood the mind's essential peace is disturbed to no avail. The way is perfect like vast space where nothing is lacking and nothing is in excess. Indeed, it is due to our choosing to accept or reject that we do not see the true nature of things. Live neither in the entanglements of outer things, nor in inner feelings of emptiness. Be serene without striving activity in the oneness of things and such erroneous views will disappear by themselves. When you try to stop activity to achieve passivity your very effort fills you with activity. As long as you remain in one extreme or the other you will never know Oneness. Those who do not live in the single Way fail in both activity and passivity, assertion and denial."
