"The hidden so-called scholars of old did not hide themselves and refuse to be seen. They did not close the door on their words and refuse to let them out. They did not shut away their wisdom and refuse to share it. But those times were all haywire. If it had been possible for them to act, they could have done great things, bringing all to Oneness without any sign of doing so. However, the times were not favorable and it was not possible, so they put down deep roots, remained still and waited. this was the Tao by which they survived."
