Says people can be attached either to existence, the outer world or emptiness, the inner void. Most of us are probably attached to existence, clinging to our thoughts, our body, the environment around us. On the other hand, someone attached to emptiness may think, since there is nothing after death, it is the simplest solution for everything. After I die, I won't have to worry about anything anymore. Another emptiness attitude may be, since the world is illusory, then nothing matters and I can stay detached from everything. Those who are attached to emptiness may have a devil may care attitude. They may refuse to take anything in life seriously, or they may even be susceptible to committing suicide. Attachment to either existence or to emptiness are improper attitudes spoken of the dangers of attachment to existence, grasping what you like and rejecting what you dislike. But to say that there is nothing to grasp and nothing to reject is also incorrect. This would be attaching to emptiness. Of course, Buddhism is known as the Middle Way. Form is emptiness. Emptiness is form. Sheng yen says a person may be meditating with a blank mind, apparently free of all thoughts and concerns. While this may seem to be approaching enlightenment, it is actually quite different. In the enlightened state, a previous thought did not arise, a future thought will not arise, and a present thought does not arise. But someone in the blank state is just sitting there, not thinking about or doing anything. In fact, he is not practicing. Indeed, he does have a thought, which is the previous thought arose, but it does not matter a future thought may arise, but again, it does not matter as to the present thought. Let it be this person may think he has no attachment to his thoughts. But actually this is far from a true state of enlightenment. This kind of state is called stubborn emptiness, as opposed to true emptiness, which is a lively state of mind full of awareness. You.
