पादे लिंगे हृदि मुखे मूर्ध्नि वक्षसि हृत्स्थले । सर्वांगे व्यापकं कुर्यादेकेन साधकोत्तमः ॥ १८ ॥
pāde liṃge hṛdi mukhe mūrdhni vakṣasi hṛtsthale | sarvāṃge vyāpakaṃ kuryādekena sādhakottamaḥ || 18 ||
เมื่อวาง (พลังมนตร์) ไว้ที่เท้า อวัยวะกำเนิด หทัย ปาก กระหม่อม อก และบริเวณหทัยแล้ว ผู้ปฏิบัติผู้ยอดเยี่ยมพึงทำให้แผ่ซ่านทั่วสรรพางค์ด้วยมนตร์เดียว.
Narada (teaching a technical ritual method within Vedanga-oriented practice)
Vrata: none
Primary Rasa: shanta
Secondary Rasa: bhakti
It teaches a disciplined inner-ritual (nyāsa) where the mantra is installed in key bodily centers and then expanded as a protective, sanctifying presence throughout the entire body (vyāpaka), turning the body into a fit vessel for sādhana.
Even in technical practice, the intent is surrender and consecration—one mantra is treated as the Lord’s living presence, first honored in specific seats and then invoked to pervade the whole being, aligning body and mind for steady devotion.
It highlights prayoga (practical ritual application) of mantra through nyāsa and vyāpaka—procedural knowledge used in mantra-vidhi to focus attention, regulate recitation, and establish ritual protection before deeper worship.
