Lying Postures

“Mendicants, there are these four ways of lying down. What four? The ways a corpse, a pleasure seeker, a lion, and a Realized One lie down. And how does a corpse lie down? Corpses usually lie flat on their backs. This is called the way a corpse lies down.

Katamā ca, bhikkhave, kāmabhogiseyyā? Yebhuyyena, bhikkhave, kāmabhogī vāmena passena senti; ayaṁ vuccati, bhikkhave, kāmabhogiseyyā.

And how does a pleasure seeker lie down? Pleasure seekers usually lie down on their left side. This is called the way a pleasure seeker lies down.

Katamā ca, bhikkhave, sīhaseyyā? Sīho, bhikkhave, migarājā dakkhiṇena passena seyyaṁ kappeti, pāde pādaṁ accādhāya, antarasatthimhi naṅguṭṭhaṁ anupakkhipitvā. So paṭibujjhitvā purimaṁ kāyaṁ abbhunnāmetvā pacchimaṁ kāyaṁ anuviloketi. Sace, bhikkhave, sīho migarājā kiñci passati kāyassa vikkhittaṁ vā visaṭaṁ vā, tena, bhikkhave, sīho migarājā anattamano hoti. Sace pana, bhikkhave, sīho migarājā na kiñci passati kāyassa vikkhittaṁ vā visaṭaṁ vā, tena, bhikkhave, sīho migarājā attamano hoti. Ayaṁ vuccati, bhikkhave, sīhaseyyā.

And how does a lion lie down? The lion, king of beasts, lies down on the right side, placing one foot on top of the other, with his tail tucked between his thighs. When he wakes, he lifts his front quarters and checks his hind quarters. If he sees that any part of his body is disordered or displaced, he is displeased. But if he sees that no part of his body is disordered or displaced, he is pleased. This is called the way a lion lies down.

Katamā ca, bhikkhave, tathāgataseyyā? Idha, bhikkhave, tathāgato vivicceva kāmehi …pe… catutthaṁ jhānaṁ upasampajja viharati. Ayaṁ vuccati, bhikkhave, tathāgataseyyā. Imā kho, bhikkhave, catasso seyyā”ti.

And how does a Realized One lie down? It’s when a Realized One, quite secluded from sensual pleasures, secluded from unskillful qualities, enters and remains in the first absorption … second absorption … third absorption … fourth absorption. This is called the way a Realized One lies down. These are the four ways of lying down.”
