烏龜的譬喻

duddante indie panca | rāga-dosa-paraṃgame /

kummo viva saṇangāiṃ | sae dehammi sāhare ||2||（Isibhāsiyāiṃ 16）

As a tortoise, when apprehensive withdraws itself into its shell,

so does an ascetic his senses to protect himself from attraction, aversion.

jahā kumme saaṅgāiṃ | sae dehe samāhare /

evaṃ pāvāiṃ mehāvī | ajjhappeṇa samāhare ||16||

sāhare hatthapāe ya | maṇaṃ pañcindiyāṇi ya /

pāvagaṃ ca parīṇāmaṃ | bhāsādosaṃ ca tārisaṃ ||17||（Sūyagaḍa 8）

As a tortoise draws its limbs into its own body,

so a wise man should cover, as it were, his sins with his own meditation. (16)

He should draw in, as it were, his hands and feet, his mind and five organs of sense,

the effect of his bad Karman, and every bad use of language. (17)（tr. by Hermann Jacobi）

Kummo aṅgāni sake kapāle,Samodahaṃ bhikkhu manovitakke;

Anissito aññamaheṭhayāno,Parinibbuto nūpavadeyya kañci.（Saṃyutta Nikāya 35.240）

龜蟲畏野干，藏六於殼內，

比丘善攝心，密藏諸覺想，

不依不怖彼，覆心勿言說。（《雜阿含》1167經）

yadā saṃharate cāyaṃ kūrmo 'ṅgānīva sarvaśaḥ |

indriyāṇīndriyārthebhyas tasya prajñā pratiṣṭhitā ||（Bhagavad Gītā 2.58）

A man's mind is steady, when he withdraws his senses from (all) objects of sense,

as the tortoise (withdraws) its limbs from all sides.
