As soon as the mouth is ...

As soon as the mouth is opened, evils spring forth. People either neglect the root and speak of the branches, or neglect the reality of the 'illusory' world and speak only of Enlightenment. Or else they chatter of cosmic activities leading to transformations, while neglecting the Substance from which they spring--indeed, there is NEVER any profit in discussion.

Quotes from the same author

Not till your thoughts cease all their branching here and there, not till you abandon all thoughts of seeking for something, not till your mind is motionless as wood or stone, will you be on the right road to the Gate.
 Huangbo Xiyun
The nature of the Absolute is neither perceptible nor imperceptible; and with phenomena it is just the same. But to one who has discovered his real nature, how can there be anywhere or anything separate from it?... ...Therefore it is said: 'The perception of a phenomenon IS the perception of the Universal Nature, since phenomena and Mind are one and the same.'
