Don't let your mind be crooked and practice straightforwardness with your lips only. We should practice straightforwardness and should not attach ourselves to anything. Such an interpretation would rank us with inanimate objects, and is a stumbling block to the right Path which must be kept open. Learned Audience, some teachers of meditation instruct their disciples to keep a watch on their mind for tranquility, so that it will cease from activity. Henceforth the disciples give up all exertion of mind.
Ignorant persons become insane from having too much confidence in such instruction.
Such cases are not rare, and it is a great mistake to teach others to do this. Those who are enlightened realize the truth in a sudden, while those who are under delusion have to train themselves gradually. But such a difference will disappear when we know our own mind and realize our own nature. Therefore these terms, gradual and sudden, are more apparent than real. Non-attachment' is the characteristic of our Essence of Mind.
