In fact, what Sakyamuni preaches here is a quiet state of mind-an extremely peaceful, quiet, harmonious and beautiful state of mind. Is this broken by any language or behavior? This kind of mentality is pure and incorruptible, free from desire and greed, calm and complacent, optimistic and self-confident, unrestrained and intangible, which will last forever in the world-that is, the so-called "truth is like a second's heart", that is, the fundamental Dharma of "illuminating everything and hiding everything"-the Dharma is hidden there. Therefore, at the Lingshan Conference, Ye Jia and Buddha were soul mates. They just talked and smiled, without any other expressions, but everything was silent, and more was told in silence than in voice. What Sakyamuni finally told Ye Jia was: "I have the Dharma, I am blind, I have two minds, I have no reality, I have subtle Buddhism, I have no words, and I will not teach outside. I will send it to you by initiation. " It is also the best proof of this mentality.
