For those into Buddhist bad-assery, no one compares to the lay practitioner, Vimalakirti. It’s one of my favorite, old-school reads.
The Vimalakirti Nirdesa Sutra, also called the Vimalakirti Sutra, probably was written nearly 2,000 years ago. Yet it retains its freshness and humor as well as its wisdom. Modern readers especially appreciate its lesson on the equality of women and the enlightenment of laypeople.
