By living our lives as messengers of the Buddha, we are involved in the Eternal Buddha’s life. Although each body cell is dying one after another through the process of metabolism, the cell is involved in one’s life and plays its own part to support that life. Similarly, while living in the world of life and death, we are involved in the Buddha’s eternal life which transcends life and death. This is a resolution of the four sufferings of birth, aging, illness and death. The beginning of Buddhism is to resolve the four sufferings of birth, aging, illness and death, and its resolution is Ichinen Sanzen.
