While there are several important things one might learn from this story [of the Magic City], its central message is quite clear: while we may think that nirvana, a condition of complete rest and quiet, is our final goal, it is not. While we may think that nirvana is salvation, that is only a useful illusion from which we will eventually need to move on. According to the Dharma Flower Sutra, it is always an illusion to think that we have arrived and have no more to do, to think that if we reach some kind of experience of happiness or comfort, we have reached the end of the path.

Similarly, while we may think that the Buddha entered final nirvana, becoming “extinct” and thus no longer active, that too is only a useful illusion, as the Buddha is working still, enabling us to live and work with him to save all the living. In Chapter 16 of the Sutra we can find these words:

In order to liberate the living,
As a skillful means I appear to enter nirvana.
Yet truly I am not extinct.
I am always here teaching the Dharma. (LS 296)

The Buddha has used teachings, including the teaching of his own final nirvana, to help people along difficult roads.
