Sutta references: (00:05) SN.35.247: “...Suppose, bhikkhus, a man would catch six animals—with different domains and different feeding grounds—and tie them by a strong rope. He would catch a snake, a crocodile, a bird, a dog, a jackal, and a monkey, and tie each by a strong rope. Having done so, he would bind them to a strong post or pillar.

Why is that? Because he sees that he could be flogged, imprisoned, fined, or blamed if he let them stray into the crops. So too I saw in unwholesome states danger, degradation, and defilement, and in wholesome states the blessing of renunciation, the aspect of cleansing…” (17:20) Mn.20: “...If, while he is giving attention to stilling the thought-sankhara of those thoughts, there still arise in him evil unwholesome thoughts connected with desire, with hate, and with delusion, then, with his teeth clenched and his tongue pressed against the roof of his mouth, he should beat down, constrain, and crush mind with mind. When, with his teeth clenched and his tongue pressed against the roof of his mouth, he beats down, constrains, and crushes mind with mind, then any evil unwholesome thoughts connected with desire, with hate, and with delusion are abandoned in him and subside.
