When positive and negative cancel reach other out you are left with dharmakaya. Reality as it is before appearing as thought, sense perception, and phenomena.

In Dzogchen, you don't use thoughts.

Because thoughts make more trouble, thoughts bring more problems, and that is

ignorance.

Why?

Because if you think, you follow thoughts and that creates something, like negative thoughts for instance. So instead, you have to look at your thoughts.

Don't try to stop them.

Don't follow them, just leave them as they are.

If a thought comes, if you leave it, it just disappears;

There is no need to go against it or try to stop it.

There is no antidote to thoughts.

Just leave it as it is.
