कृत्वाङ्गन्यासमेवं हि मुखानि परिकल्पयेत् पूर्वादि चोर्ध्वपर्यन्तं नकारादि यथाक्रमम्
kṛtvāṅganyāsamevaṃ hi mukhāni parikalpayet pūrvādi cordhvaparyantaṃ nakārādi yathākramam
このようにアṅガ・ニヤーサを成したのち、東方より始めて上方(天頂)に至るまで、神聖なる諸面を観想し、音節「na」を起点として真言の順序に従い次第に配当すべきである。
Suta Goswami (narrating the Puja-vidhi to the sages of Naimisharanya)
It instructs that after aṅga-nyāsa, the worshipper should perform a structured visualization/assignment of Shiva’s directional faces, aligning the rite with mantra-order (nakārādi), thereby making the Linga-puja an ‘installed’ presence rather than a mere external offering.
Shiva is approached as Pati who pervades all directions and transcends them (reaching ‘ūrdhva’), and is accessed through mantra-śakti—His aspects are ritually ‘conceived’ so the bound soul (paśu) can orient mind and prāṇa toward the all-pervading Lord.
Aṅga-nyāsa followed by dik/ūrdhva-vinyāsa (directional arrangement of faces/aspects) keyed to a mantra-syllable sequence (nakārādi), a practice that supports Pashupata-style inner purification and focused worship.
