The point is not to mix up true zazen practice with some other practice like something intellectual because the way we study is quite different. Intellectual study or a physical or an emotional friend also. In those activities or studies our effort is directed to attain something. But in zazen practice our effort is directed in an opposite way. To forget or to stop all thinking and to resume our original mind—the most, inmost content of our mind, before thinking—before we feel something.
