Sandhyā-Upāsanā Vidhi: Prāṇāyāma, Water Purification, Aghāmarpaṇa, Sūrya Worship, Nyāsa, and Gāyatrī Japa
पूर्वसंध्यां जपंस्तिष्ठेत्पश्चिमामुपविश्य च / महाव्याहृतिसंयुक्तां गायत्त्रीं प्रणवान्विताम्
pūrvasaṃdhyāṃ japaṃstiṣṭhetpaścimāmupaviśya ca / mahāvyāhṛtisaṃyuktāṃ gāyattrīṃ praṇavānvitām
पूर्वसन्ध्यायां जपंस्तिष्ठेत् पश्चिमायामुपविश्य च। महाव्याहृतिसंयुक्तां प्रणवपूर्वां गायत्रीं जपेत्॥
Lord Vishnu (in instruction to Garuda/Vinata-putra)
Concept: Proper sandhyā-japa discipline: stand for morning sandhyā, sit for evening; recite Gāyatrī with mahāvyāhṛtis and praṇava.
Vedantic Theme: Praṇava and vyāhṛtis as pointers to Brahman and the three worlds; mantra-japa as mind-purification and concentration leading toward jñāna.
Application: Keep consistent dawn/dusk practice; maintain correct posture, breath, and attention; include Oṃ and bhūr-bhuvaḥ-svaḥ (and extended vyāhṛtis per tradition) with Gāyatrī as taught in one’s śākhā.
Primary Rasa: shanta
Secondary Rasa: vira
Type: threshold time/space (twilight)
Related Themes: Garuda Purana 1.36 (sequence of sandhyā, aghāmarpaṇa, Sūrya-upasthāna, gāyatrī-japa)
This verse frames Sandhyā as a disciplined daily duty: correct posture and the proper form of Gāyatrī-japa (with Oṃ and the vyāhṛtis) are presented as a dharmic observance that purifies and steadies the practitioner.
Indirectly: by prescribing daily purification through Gāyatrī with Praṇava and vyāhṛtis, it emphasizes inner purity and right conduct—foundational causes (karma and saṃskāra) that shape one’s post-death trajectory described elsewhere in the Purana.
Keep a consistent dawn-and-dusk practice: stand for morning japa, sit for evening japa, and chant Gāyatrī in the traditional sequence including Oṃ and the vyāhṛtis, as a daily discipline of clarity and restraint.
