Renunciation is the root of liberation. It is the decision to be free from the repeating cycles of rebirth, sickness, old-age and death, to be free from the uncontrollably spinning wheel, to be free from samsara. Liberation becomes possible when renunciation has arisen in your awareness.
I learned from my teachers that one possible translation into English of the Tibetan word for renunciation is “definite emergence”. There is a sense of great urgency about renunciation. A metaphor that is sometimes used is that your renunciation—your decision to be free from samsara—should be as strong as if you were standing in a fire and wanted to get out of it. There is no debating (Do I want to get out? Maybe I will get out tomorrow?), it is direct, immediate, and determined. Sometimes this immediacy is described as being a ‘”spontaneous” motivation, meaning that it arises naturally and without obstruction. More often, renunciation is something that requires cultivation.
Deeply and carefully reflecting on the Four Thoughts that Turn the Mind Toward the Dharma—the precious human rebirth, impermanence and death, the nature of suffering, and karma—aids in the cultivation of renunciation. Taking refuge in the Buddha, Dharma and Sangha is only possible with renunciation, because you must first be determined to be free of suffering before you can actively and meaningfully embrace the Three Jewels as reliable supports for liberation. In addition, we need renunciation to be able to generate Bodhicitta, the Mind of Enlightenment, or the Great Compassion.
