基本上，空是能平息下来，以一种特殊的想的方式将心专于一处，保持一境，然后专注于这种方式中扰动的生灭。

Essentially, it boils down to the ability to center the mind in a particular mode of perception, to maintain it there, and then to notice the absence and presence of disturbance within that mode.

忘了外在的我，忘记了生生灭灭，从这过程中恍恍惚惚看到内在的我、不动的心。

Forget about what is produced and what is destroyed in the mind. In the process of flip-flopping of mental states, one may see the inner self, the unmoving mind.

由于心中有迁流、有生灭，身体就跟著这一念心在生生灭灭，因此就感生、老、病、死。

Because the mind is changing and flowing, arising and ceasing, the body follows the mind by coming into and ceasing from existence. Therefore we experience birth, aging, illness and death.
