Today is the sixth 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.

The today we consider the Perfection of Meditation.

The ideal of this fifth perfection is to live in a meditative frame of mind regardless of whether we happen to be meditating. The goal, therefore, is not always to be meditating, always to be practicing a preparatory activity, but rather to live in the spirit of composure and insight that the practice has produced.
