"The vast wisdom is as true as the sea of ??nature, and it is full of enlightenment." Vast wisdom is the wisdom of Buddha. The sea of ??true nature is the realm of Buddha. Upon attaining enlightenment, we reach the stage of practice of Buddha wisdom and the Buddha realm. Sun Wukong was born very smart, that is "ying", but he still couldn't let go, so he was trapped in the palm of Tathagata's hand, pressed under the Five Elements Mountain, and imprisoned by the golden hoop. Therefore, the Bodhi Patriarch asked him to realize the emptiness. Of course, if he becomes emptied, nothing will exist. But after emptiness, wisdom is not yet perfect, it still needs to be "rounded", and finally it can reach the "enlightenment" of Buddha. Of course, you don’t have to do these steps.
We already possess vast wisdom and the ocean of true nature. "The Sutra of Perfect Enlightenment" says: "Knowing the illusion is the moment you get rid of it. If you don't make convenient methods, getting rid of the illusion is the moment you wake up. There is no gradual way."
Haha, I have no intention of sleeping, I am talking nonsense!
