Praise of Ācāra as the Basis of Longevity, Fame, and Prosperity
तस्मात् तिछेत् सदा पूर्वा पश्चिमां चैव वाग्यतः । ग्रहण और मध्याह्नके समय भी सूर्यकी ओर दृष्टिपात न करे तथा जलनमें स्थित सूर्यके प्रतिबिम्बकी ओर भी न देखे। ऋषियोंने प्रतिदिन संध्योपासन करनेसे ही दीर्घ आयु प्राप्त की थी। इसलिये सदा मौन रहकर द्विजमात्रको प्रात:काल और सायंकालकी संध्या अवश्य करनी चाहिये
tasmāt tiṣṭhet sadā pūrvāṃ paścimāṃ caiva vāgyataḥ | grahaṇe madhyāhnake kāle ca sūryasya na dṛṣṭipātaṃ kuryāt, jalasthaṃ sūryapratibimbaṃ ca na paśyet | ṛṣayaḥ pratidinaṃ sandhyopāsanenaiva dīrgham āyuḥ prāpuḥ | tasmāt sadā maunaṃ kṛtvā dvijamātreṇa prātaḥkāla-sāyaṃkāla-sandhyā nityaṃ kartavyā ||
毗湿摩说道：“因此，当常以言语与行止自律，守其正向，持其节制。日食之时与正午之际，不可仰视太阳；亦不可观其在水中所现之日影。诸仙贤之所以得长寿，正因每日修行暮旦交界之礼——沙恩迪亚（sandhyā）敬拜。故而，持默守制，一切二次生者皆当不失其时，必行晨夕之沙恩迪亚仪轨。”

Educational Q&A
Bhīṣma emphasizes disciplined restraint—especially control of speech and senses—and prescribes daily sandhyā observance as a sustaining dharmic practice, associated with purity, longevity, and steadiness of life.
In Anuśāsana Parva, Bhīṣma continues instructing Yudhiṣṭhira on dharma. Here he gives practical rules of conduct—avoiding gazing at the sun at certain times and maintaining regular sandhyā worship—presented as traditional guidance validated by the example of the ṛṣis.
