Most Buddhists know that a bodhisattva is someone who helps others through their understanding of “enlightened practice” or “enlightening practices.” The Buddha is called a bodhisattva when referring to the time before he became a Buddha.
A bodhisattva uses wisdom to do compassionate work or “generous” work, to use the terminology of the Diamond Sutra. Strictly speaking, “generosity” in the Diamond Sutra means sharing the Dharma with others, but in practice this concept can, of course, take many forms. For example, maybe just being nice to someone will help them more than an extensive Dharma talk.
It is possible when studying the Diamond Sutra to experience a kind of spiritual ecstasy or meditative ecstasy as one contemplates the fulsome purity of mind that attends the selfless generosity discussed in the sutra. At such times, you know without doubt that this is a higher state of mind, a better way to be; it feels like a genuine glimpse of Buddhahood, of the enlightened state of a Buddha.
I for one have no doubt that those states are higher and realer than the mundane states of mind we so often are consigned to. But it is important to understand that the Diamond Sutra is not only about being generous. It is also about being wise.
In all Buddhist traditions at all times, the highest virtue is always wisdom.
A well-known analogy is often used to explain this. If you want to save someone who is drowning you must know how to swim. If you can’t swim and you jump in the water, you will not only not help but probably lose your own life as well.
Generosity must be tempered with wisdom. The Diamond Sutra is not about moral idealism or the belief that “individual rights and responsibilities are universal, regardless of outcome.”
Buddhist teachings are all about good outcomes. The point of Buddhist practice is to become enlightened. When we glimpse the bliss of pure selfless generosity, we are glimpsing Buddhahood. But at that point we are still merely bodhisattvas, at best. In this world, absolutely pure, selfless behavior can get you robbed and killed. So you need some smarts, a sense of what really can be done to get real outcomes. Even terrible reprobates can be helped and can change, but don’t be foolish about your chances for success or the methods you use.
