A prisoner locked in jail thinks all the time about different ways of getting free

 

(from "The Heart of Compassion"): 

Dilgo Khyentse Rinpoche: It is not enough to wish from time to time that you could be free of samsara. That idea must pervade your stream of thinking, day and night.

A prisoner locked in jail thinks all the time about different ways of getting free—how he might climb over the walls, ask powerful people to intervene, or raise money to bribe someone. So, too, seeing the suffering and imperfection of samsara, never stop thinking about how to gain liberation, with a deep feeling of renunciation.
