The Way is basically perfect. It doesn't require perfecting. The Way has no form or sound. It's subtle and hard to perceive. It's like when you drink water: you know how hot or cold it is, but you can't tell others.
Leaving behind the false, return to the true: make no discriminations between self and others. In contemplation, one's mind should be stable and unmoving, like a wall.
This one life has no form and is empty by nature. If you become attached by any form, you should reject it. If you see an ego, a soul, a birth, or a death, reject them all.
The awareness of mortals falls short. As long as they're attached to appearances, they're unaware that their minds are empty. And by mistakenly clinging to the appearance of things they lose the Way.
But this mind isn't somewhere outside the material body of the four elements. Without this mind we can't move. The body has no awareness. Like a plant or a stone, the body has no nature. So how does it move? It's the mind that moves.
All Buddhas preach emptiness. Why? Because they wish to crush the concrete ideas of the students. If a student even clings to an idea of emptiness, he betrays all Buddhas.
If you use your mind to study reality, you won't understand either your mind or reality. If you study reality without using your mind, you'll understand both.
