In Buddhism, a thought has many names: truth, self-nature, dharma body, reality, Buddha nature, dharma nature, Tathagata hiding, perfection, true colors, local scenery, great round mirror wisdom and so on. Sincere and incredible, that is, Zen Buddhism's "being tempted is good, being tempted is destroyed", that is, Zen Buddhism's "opening your mouth is wrong, and words are broken". Here, I have to quote a far-fetched metaphor from master lianchi: "The heart is invisible, so there is nothing to compare. Generally speaking, the metaphor of the heart is a last resort. Let's describe it as similar to the function of the heart, so that people can understand the concept of the heart, but we can't think that the heart is really like something. For example, compare the heart to a mirror. As we all know, mirrors can reflect things. When things do not face the mirror, the mirror will not bring the image of things into the mirror. When things are facing the mirror, the mirror will not hate them because of their likes and dislikes, beauty and ugliness; When an object leaves the mirror, the mirror will not retain the image of the object in the mirror. The heart of the sage is always silent, always shining, spotless, and there are photos everywhere. This heart is not inside, not outside and not in the middle. San Ji is empty, but it's all-encompassing, and nothing doesn't shine. Therefore, using a mirror to compare the heart is just taking its similarities. After all, the mirror is an unconscious object. Is the mind as ignorant as a mirror? And the mirror has lost its function in the dark, how can it be compared with the wonderful real body that is always silent and often shines? By analogy, the reason is the same, whether it is to use the orb to compare the heart or to use emptiness to compare the heart.

You got it? Amitabha!
