The Buddha’s words “I observe that length of time as if it were only today” suggest to us that human life is unlimited. The Buddha gives us hints to realize that our lives continue from the unlimited past to the endless future; “today” does not exist in isolation but is like a deep pool or a shoal of the endless river of life. If we defile our body and mind of today, we exert a bad influence upon the lower reaches of the stream of unlimited life. If we purify our body and mind of today, we cause a favorable change farther down the same stream.
