All the mind’s arbitrary concepts of matter, phenomena, and of all conditioning factors and all conceptions and ideas relating thereto are like a dream, a phantasm, a bubble, a shadow, the evanescent dew, the lightning’s flash. Every true disciple should thus look upon all phenomena and upon all the activities of the mind, and keep his mind empty and selfless and tranquil.
~The Diamond Sutra
If we can speak about the "usual" meaning of a word, then in another instant use the word in an "extraordinary" manner the true nature of all words is emptiness, and the mind fills them with meaning. We may engage in intellectual exercises where we seek to grasp "concepts" by putting them into words we find "believable", but that does not change the nature of the dream.It happened that one day, when a pennant was blown about by the wind, two Bhikkhus entered into a dispute as to what it was that was in motion, the wind or the pennant. As they could not settle their difference I submitted to them that it was neither, and that what actually moved was their own mind.
~The Platform Sutra of Hui Neng
This is a very "mind-blowing" discussion!!!
