त्वष्ट्रा युतं पद्मनाभं दामोदरं च विष्णुना । द्वादसार्णं ततो मंत्रं समस्ते शिरसि न्यसेत् ॥ २७ ॥

Bấy giờ, hành giả nên làm nyāsa, an đặt thần chú mười hai âm lên đỉnh đầu, thỉnh Padmanābha cùng với Tvaṣṭṛ, và Dāmodara cùng với Viṣṇu.
Sanatkumara (teaching Narada)
Vrata: none
Primary Rasa: bhakti
Secondary Rasa: shanta
It teaches śiro-nyāsa—placing the mantra on the head—signifying surrender of one’s intellect and identity to Viṣṇu, so the practitioner’s awareness is ritually aligned with the deity before further japa or worship.
By invoking Viṣṇu’s names (Padmanābha, Dāmodara, Viṣṇu) within a disciplined ritual act, the verse shows bhakti as both loving remembrance (nāma) and careful observance (vidhi), making devotion steady and embodied.
It highlights mantra-vidhi and nyāsa (ritual assignment of mantra to body-parts), a technical discipline aligned with śikṣā (correct recitation) and kalpa-style procedural worship found in Narada Purana’s practical instructions.
