गृहस्थस्य सदाचारः: शौच, तर্পण, वैश्वदेव, अतिथिधर्म, भोजन-विधि, संध्योपासन, ऋतु-धर्मः
उपतिष्ठन्ति ये संध्यां न पूर्वां न च पश्चिमाम् व्रजन्ति ते दुरात्मानस् तामिस्रं नरकं नृप
upatiṣṭhanti ye saṃdhyāṃ na pūrvāṃ na ca paścimām vrajanti te durātmānas tāmisraṃ narakaṃ nṛpa
Wahai raja, mereka yang berhati rusak yang tidak menunaikan Sandhyā, baik yang pagi maupun yang petang, akan pergi ke neraka Tāmisra, alam kegelapan yang membutakan.
Sage Parāśara (in discourse, addressing a kingly addressee within the teaching)
This verse treats Sandhyā as a foundational daily duty; neglecting both dawn and dusk worship is presented as a serious breach of dharma with severe karmic consequences.
Parāśara frames omission of obligatory practices as moral and spiritual decline (durātmānaḥ), leading to specific post-death outcomes such as Tāmisra, emphasizing karma’s governance of cosmic justice.
Even when Vishnu is not named, the teaching presumes a Vishnu-governed moral cosmos where dharma sustains order; daily rites align the individual with that supreme, sustaining reality.
