Hui Neng

One should use one's mind in such as way free one's mind from any attachment.
For him who does not know his own mind there is no use learning Buddhism.
Refrain from thinking of anything and keep your mind blank.

Empty my mind, no useless thinking.
Hui Neng is the first to mention Dialectics.
Show something more than book- knowledge.

There can not be two ways in Buddhism.

As far as Buddha nature is concerned there is no difference between intelligent and ignorant one.

Meditation is to see the internal original nature and not to be confused.
No thought: even you see all the things, you remain unattached to them.
