Mahabharata — Anushasana Parva, Shloka 27
आचारप्रशंसा
Praise of Ācāra as the Basis of Longevity, Fame, and Prosperity
चतुष्पथान् प्रकुर्वीत सवनिव प्रदक्षिणान् । मार्गमें चलते समय अश्वत्थ आदि परिचित वृक्षों तथा समस्त चौराहोंको दाहिने करके जाना चाहिये ।। मध्यन्दिने निशाकाले अर्धरात्रे च सर्वदा
catuṣpathān prakurvīta savaniva pradakṣiṇān | mārgam̐ me calte samaya aśvattha-ādi paricita vṛkṣoṃ tathā samasta caurāhoṃ ko dāhine karke jānā cāhiye || madhyandine niśākāle ardharātre ca sarvadā
毗湿摩说：当以恭敬之心对待四衢路口，行走经过时使其在自己右侧，犹如行右绕礼一般。旅行之时，也应当使圣阿湿瓦塔（aśvattha，菩提/榕属）等熟知之树以及一切路口皆在右侧而过。此等恭敬之法当恒常奉行——正午、夜间、半夜，乃至一切时刻。

Educational Q&A
Maintain auspicious and respectful conduct in everyday movement: when passing sacred or socially significant points like crossroads and revered trees (e.g., aśvattha), keep them on the right as a sign of reverence (pradakṣiṇā), and observe this consistently at all times.
In the Anuśāsana Parva, Bhīṣma is instructing Yudhiṣṭhira on dharma and proper conduct (sadācāra). Here he gives practical guidance for travellers—how to move past crossroads and sacred trees in an auspicious, respectful manner.
