Fire is hot; water, cold.

Nobody guarantees our life. So if there is anything that you think may be useful, just now is the time to use it. In our life, past mind cannot be attained. Present mind cannot be attained. If you say “present,” it is already not present, already gone.
Any kind of formal practice is a simple situation in which it is easier to cut off thinking. As we do formal practice, it will start to affect our everyday life. Any moment in our life can be understood as a kong-an.
