सूर्यं च मूर्ध्नि वदने हृदि गुह्ये च पादयोः । सद्यादिपञ्च ह्रस्वाद्यान् न्यसेन्ङे हृदयोंऽतिमान् ॥ ८ ॥
sūryaṃ ca mūrdhni vadane hṛdi guhye ca pādayoḥ | sadyādipañca hrasvādyān nyasenṅe hṛdayoṃ'timān || 8 ||
行者はニヤーサ(nyāsa)によって、スーリヤ(Sūrya、太陽神)を頭頂・口・心臓・秘所・両足に安置し、さらに「sadya…」に始まる五つの真言を短母音および他の音とともに順次に置いて、規定の次第でハリダヤ・ニヤーサ(心のニヤーサ)を成就すべきである。
Sanatkumara (in instruction to Narada, within Vedanga/ritual context)
Vrata: none
Primary Rasa: shanta
Secondary Rasa: bhakti
It teaches nyāsa—sacralizing the practitioner’s body by assigning divine power (here, Sūrya and a pentad of mantras) to specific loci, making the body a fit support for mantra-japa and ritual contemplation.
By prescribing embodied worship: devotion is expressed not only as feeling but as disciplined ritual remembrance, where the deity is invoked and honored in the very limbs and vital centers before further practice.
Ritual-technical practice linked to Vedāṅga application—precise mantra placement (nyāsa), phonetic elements like short vowels (hrasva), and ordered limb-mapping used in formal worship and mantra-sādhana.
