相応部（サンユッタ・ニカーヤ） 2:5
SUJATOYo cāyaṁ kāmesu kāmasukhallikānuyogo hīno gammo pothujjaniko anariyo anatthasaṁhito, yo cāyaṁ attakilamathānuyogo dukkho anariyo anatthasaṁhito.
Indulgence in sensual pleasures, which is low, crude, ordinary, ignoble, and pointless. And indulgence in self-mortification, which is painful, ignoble, and pointless.
