Tonglen is a Practice and a Way of Life
Traditionally, we begin by doing Tonglen for someone we care about. However, we can use this practice at any time, either for ourselves or others.
Tonglen can be done for those who are ill, those who are dying or have just died, or for those that are in pain of any kind.
Tonglen can be done either as a formal meditation practice or right on the spot at any time. For example, if we encounter someone in pain, right on the spot we can begin to breathe in their pain and send out some relief.
At any time, when we encounter our own emotional discomfort or suffering, or that of others, we open our heart and fully embrace what we are encountering on our in-breath. Breathing out, we offer the heartfelt radiance of acceptance, loving-kindness, and compassion. This is a practice and a way of life.
Practicing Tonglen on one friend in pain helps us begin the process of gradually widening the circle of our compassion. From there, we can learn to take on the suffering and purify the karma of all beings; giving others our happiness, well-being, joy, and peace of mind. Tonglen practice can extend indefinitely, and gradually, over time, our compassion will expand. We will find that we have a greater ability to be loving and present for ourselves and for others in even the most difficult situations. This is the wonderful goal of Tonglen practice, the path of the compassionate Bodhisattva.
