In practicing the slogans and in your daily life, you should maintain an awareness of

[1] the preciousness of human life and the particular good fortune of life in an environment in which you can hear the teachings of Buddhadharma;

[2] the reality of death, that it comes suddenly and without warning;

[3] the entrapment of Karma - whatever you do, whether virtuous or not, only further entraps you in the chain of cause and effect; and

[4] the intensity and inevitability of suffering for you and for all sentient beings.

This is called "taking the attitude of the four reminders"
