उपदेशदोषप्रसङ्गः (Upadeśa-doṣa-prasaṅgaḥ) — The Risk of Misapplied Counsel
कुरुष्वैतां पूर्वशीर्षा भवांश्वोदड्मुख: शुचि: । सच तत् कृतवान् शूद्र: सर्व यदृषिरब्रवीत्
kuruṣvaitāṃ pūrvaśīrṣā bhavāñ chvodāṅmukhaḥ śuciḥ | sa ca tat kṛtavān śūdraḥ sarvaṃ yad ṛṣir abravīt ||
毗湿摩说道:“把这俱舍草席的首端朝向东方;你既已净身,当面向北方而坐。”那首陀罗便依圣仙所言,事事照办,无一违失。

Dharmic practice requires disciplined attention to right procedure—purity, proper orientation, and faithful execution of a teacher’s instructions—showing that ethical seriousness is expressed through careful conduct (ācāra).
A sage instructs a Śūdra to arrange a kuśa seat with its end toward the east and to sit purified facing north; the Śūdra complies fully with everything the sage says, and Bhīṣma recounts this as part of his discourse on right conduct.
