Jñāna-yoga and Karma-phala: Manu–Bṛhaspati on Akṣara and the Limits of Mantra
श्मश्रुकर्मणि सम्प्राप्ते क्षुते सनाने5डथ भोजने । व्याधितानां च सर्वेषामायुष्यमभिनन्दनम्
śmaśrukarmaṇi samprāpte kṣute snāne ’tha bhojane | vyādhitānāṃ ca sarveṣām āyuṣyam abhinandanam ||
毗湿摩说道：剃须理发之后、打喷嚏之后、沐浴之后、进食之后——同样地，对于一切为疾病所困之人——以恭敬之礼致敬并致以善愿（尤其向婆罗门）乃是增益寿命之责。此等虔敬的问候被称颂为能致长寿与安康。

Educational Q&A
Cultivating respectful greetings and salutations—particularly toward Brāhmaṇas—at key daily moments (after grooming, sneezing, bathing, and eating) is presented as dharmic conduct that supports health, auspiciousness, and longevity, even for the sick.
In Śānti Parva, Bhīṣma instructs on righteous living and proper conduct. Here he lists everyday occasions and prescribes abhinandana (courteous salutations/blessings) as a beneficial observance tied to well-being and long life.
