Visuddhimagga IV-18

Kalyāṇamittānaṃ alābhoti yattha na sakkā hoti ācariyaṃ vā ācariyasamaṃ vā upajjhāyaṃ vā upajjhāyasamaṃ vā kalyāṇamittaṃ laddhuṃ. Tattha so kalyāṇamittānaṃ alābho mahādosoyevāti imesaṃ aṭṭhārasannaṃ dosānaṃ aññatarena samannāgato ananurūpoti veditabbo.

18.「不得善友」的精舍，是说不可能获得善友 ── 如阿阇梨或阿阇梨同等者、和尚或与和尚同等者的地方。不得善友是大过失。于此等十八种过失中，具有任何种类的，当知便是不适当的精舍。

Ñ(IV,18): 18. Lack of good friends: where it is not possible to find a good friend as a teacher or the equivalent of a teacher or a preceptor or the equivalent of a preceptor, the lack of good friends there is a serious fault. One that has any of those eighteen faults should be understood as unfavourable.

Vuttampi cetaṃ aṭṭhakathāsu –

在义疏中亦曾这样说：

Ñ: And this is said in the commentaries:

Mahāvāsaṃ navāvāsaṃ, jarāvāsañca panthaniṃ;

大寺与新寺，

古寺及路旁，

Ñ: 'A large abode, a new abode,

One tumbling down, one near a road,

Soṇḍiṃ paṇṇañca pupphañca, phalaṃ patthitameva ca.

有泉菜花果，

为人渴仰者，[PTS 122]

Ñ: One with a pond, or leaves, or flowers,

Or fruits, or one that people seek; [122]

Nagaraṃ dārunā khettaṃ, visabhāgena paṭṭanaṃ;

近城与林田，

或住不和者，

近于贸易场，

Ñ: In cities, among timber, fields,

Where people quarrel, in a port,

Paccantasīmāsappāyaṃ, yattha mitto na labbhati.

或边疆国界，

不妥之住处，

不得善友者，

Ñ: In border lands, on frontiers,

Unsuitableness, and no good friend —

Aṭṭhārasetāni ṭhānāni, iti viññāya paṇḍito;

此等十八处，

智者知之已，

Ñ: These are the eighteen instances

A wise man needs to recognize

Ārakā parivajjeyya, maggaṃ sappaṭibhayaṃ yathāti.

自应远离之，

如避险恶道。

Ñ: And give them full as wide a berth

As any footpad-hunted road'.
