In [Chapter 5] the Buddha uses the example of medicinal herbs. Throughout the worlds there are innumerable valleys, fields, and gardens that contain countless species of plants. Every species has its own name and character, its own life cycle, its specific strengths and properties. None is exactly like another. Living beings are the same. They are of many different types. The sphere of activities of one person is like this; the social circumstance of another person is like that. Living beings are thus like the innumerable kinds of plants that grow in different environments.

One day the clouds came and covered the entire cosmos, and rain fell on all the species of plants. Some plants were very small with slim branches, some were very large with broad leaves, and some were neither small nor large. There were so many species, so many types of plants, yet they all benefited fully from the rain, each according to its own needs and capacity.

The teachings of the Buddha are like this. The rain of the Dharma falls not just on one class or type of human being. Whether they are shravakas, pratyekabuddhas, or bodhisattvas, monastics or laypeople, nobles or peasants, workers or warriors, male or female, child, youth, adult, or elder – all beings benefit from the Tathagata’s teachings. The Dharma is universal and has the capacity to serve all kinds of people, not just one social class, one nation, or one kind of understanding.
