Today is the second day of Higan week, the three days before the equinox and the three days after. As explained in a Nichiren Shu brochure:

For Buddhists, this period is not just one characterized by days with almost equal portions of light and dark. Rather, it is a period in which we strive to consciously reflect upon ourselves and our deeds.

Today we consider perfection of discipline:

Like most of us, bodhisattvas at earlier levels of practice assume that things stand on their own and can therefore be grasped in isolation from other things. They take the language of things to validate a certain understanding of things and cannot at the outset think otherwise. But the practice of the perfections is meant to disrupt that understanding and to show how the depth of things is more truthfully disclosed through the “emptiness” of linguistic signs and their referents. …

The realization that all moral rules are “empty” works toward freeing the bodhisattva from an inappropriate attachment to them. Holding the rules in one’s mind without “clinging” to them, without “grasping” them dogmatically, yields a certain degree of latitude in their practice. The moral rules are understood as means, not ends, and when these means come into conflict with important ends, the bodhisattva learns to practice the rules flexibly.
