The study of knowledge is the study of filling, and the study of mind is the study of emptying. Mind study should be the opposite of knowledge study. Mind study is not a study to fill knowledge, but a study to empty what you know. To study the mind, you must put down the thought that you know and empty your mind.
Mind study can be done well when you put your thoughts down. You can do well when you let go of your greed. You can do well when you let go of your attachments. Mind study begins when you put down your thoughts, greed, and obsession. Drop all thoughts that I know.
I wish you to empty your mind and live comfortably.
