The Explanation of Sandhyā and Related Daily Observances
Saṅdhyā-ādi Nitya-karma-Vidhi
पृष्ठवंशे वमित्युक्तं नाभौ भं हृदये तु मम् । यादिसप्तापि धातुस्था हं प्राणे लं तथात्मनि ॥ १०५ ॥
pṛṣṭhavaṃśe vamityuktaṃ nābhau bhaṃ hṛdaye tu mam | yādisaptāpi dhātusthā haṃ prāṇe laṃ tathātmani || 105 ||
يُقال إن «vaṃ» يُوضَع في العمود الفقري؛ و«bhaṃ» في السُّرّة؛ و«maṃ» في القلب. وكذلك فإن الحروف السبعة المبتدئة بـ«ya» تستقر في الدهاتو (مكوّنات الجسد)؛ و«haṃ» في البرانا (النَّفَس الحيوي)؛ و«laṃ» في الآتمان (الذات).
Sanatkumara (teaching Narada in a Vedanga/technical context of mantra-nyasa)
Vrata: none
Primary Rasa: shanta
Secondary Rasa: adbhuta
It presents a nyāsa-style inner mapping of mantra-syllables onto the body—spine, navel, heart, dhātus, prāṇa, and ātman—showing how recitation is internalized as a yogic-sacred physiology aimed at purification and realization.
By prescribing internal placement of sacred sounds, it turns mantra-japa into an embodied act of remembrance; such inward worship supports steady devotion by linking breath, heart, and self to continuous mantra-awareness.
It reflects Śikṣā (phonetics/mantra-sound discipline) and allied mantra-vidyā: precise syllable identification (e.g., ya-varga group) and their ritual-yogic application through nyāsa with prāṇa and bodily dhātus.
