Having last month considered the Buddha’s realization that not everything should be explained, we consider how water is like the Dharma.
“O you of good intent! The Dharma is like water that can wash away dirt and grime. Whether coming from a well or a pond, a stream or a river, a valley or a ditch, or an ocean, the water contained in all of these can effectively wash all kinds of dirt and grime away. So it is also with the water of the Dharma: it can cleanse living beings of the dirt of all delusive worldly passions. O you of good intent! The character of the water is the same even though streams, rivers, wells, ponds, valleys, ditches, and oceans are each different and distinct. So it is also with the character of the Dharma: it removes and washes away the dirt of delusive passions equally and without discrimination; the three teachings,14 the four fruits, and the two ways, however, are not one and the same.
“O you of good intent! Although the water from all of these places is cleansing, a well is not a pond, a pond is neither a stream nor a river, and valleys and ditches are not oceans. The Tathāgata—Hero of the World, in total command of the Dharma—has expounded various teachings that are also like this. The initial-period discourses, the middle-period discourses, and the latter-period discourses are all able to remove and wash away delusive worldly passions of living beings. But the initial-period discourses are not the middle ones, and the middle-period discourses are not the latter ones. The initial-, middle-, and latter-period discourses express the same thing, yet they differ from each other in meaning.
