وبتقسيم الطقس إلى ثلاثة أنحاء—ابتداءً بنمط النشوء—فليؤدِّ النْياسا على الترتيب الصحيح بحسب آشرمَه (āśrama) الخاص به. وبكلتا اليدين وحدهما يلمس ويضع قوة المانترا من أخمص القدمين إلى قمة الرأس.

It establishes nyāsa as a mandatory inner preparation for Linga-pūjā—consecrating the entire body as a fit seat for Shiva’s mantra-power before external offerings.
By directing mantra-placement through the whole body, it implies Shiva as Pati pervading and sanctifying the pashu (individual soul-body complex), loosening pāśa (bondage) through ordered discipline.
A full-body nyāsa performed sequentially—from the soles to the crown—done with both hands, adapted to one’s āśrama, aligning with Pāśupata-oriented purification before worship.
