अस्रं रक्षद्वयं सर्वे हुमंताः समुदीरिताः । मस्तके नेत्रयोः कंठहृदये नाभिदेशके ॥ ९९ ॥
asraṃ rakṣadvayaṃ sarve humaṃtāḥ samudīritāḥ | mastake netrayoḥ kaṃṭhahṛdaye nābhideśake || 99 ||
எல்லா ‘அஸ்த்ர’ பாதுகாப்பு மந்திரங்களையும், இருவகைப் பாதுகாப்பையும் ‘ஹும்’ எனும் உச்சரிப்புடன் சொல்ல வேண்டும். பின்னர் தலை, கண்கள், தொண்டு, இதயம், நாபிப் பகுதி ஆகிய இடங்களில் ந்யாசம் செய்ய வேண்டும்.
Narada (teaching within a technical/ritual instruction context, traditionally in dialogue line with Sanatkumara tradition)
Vrata: none
Primary Rasa: shanta
Secondary Rasa: vira
It teaches mantra-based protection through nyāsa: sacred sound is consciously placed on key bodily centers to guard the practitioner and stabilize the rite.
Though technical, it supports devotion by safeguarding worship: the devotee uses mantra-protection so the mind and senses remain steady for focused remembrance and worship.
Ritual procedure (prayoga) and mantra-application (nyāsa/anga-nyāsa) are highlighted—how to utter bija-like exclamations such as “hum” and place protection on specific body points.
