The highest truth cannot be put into words. Therefore the greatest teacher has nothing to say. He simply gives himself in service, and never worries.
Walker's HHC 23
“Kind Prince, please do not suppose that a universal being imposes any particular religious doctrine on people. If someone says that a universal being sets up a particular religious teaching to transmit the truth, he is ignorant of the Universal Way and does not truly understand what I have said. The most achieved of teachers actually has nothing to say. Although what he teaches may be called the highest truth, the reality can never be put into words.”
At that time the prince asked the master, “Venerable Teacher, when people hear this truth in the future, will they be able to follow it?”“Kind prince, do not worry about whether there will be people to follow it or not. An integral universal being knows that nothing which can be put into words is the integral truth. He does not ask people to follow, his only interest is to serve. He does not indulge in worry, but simply does his work. This is called ‘doing that which is done by not-doing.’”
