Another goal that teachers like to hold up as important is Truth, and I have a few words to offer about that as well.
“No thought is true.”
— Ram Dass
It seems to me that Ram Dass is right about that, the contents of the mind are essentially concerned with the world or with other thoughts, and it is all impermanent. Lao Tzu was on this path as well, “the Tao that can be spoken is not the Tao.” It is tempting to think that the mind can produce thoughts which are true, such as ‘what goes up must come down’, but it’s all just play of the mind and the world.
If you regard the truth of our existence then I think the dhamma comes closest. There are areas of being where an education in the dhamma fundamentally changes the way you perceive things, whether they are of this world or another world. But even then they are still thoughts, subject to disappearing when the body dies.
Real, lasting Truths seem to me to be linked to being, not thinking.
