其韵律当知;圣仙(ṛṣi)为婆罗陀婆阇(Bharadvāja);主宰神祇被称为斯甘达(Skanda)。今我将宣说此之安置法(nyāsa),吉祥而能成就一切悉地。
Suta Goswami (narrating to the sages at Naimisharanya)
It establishes the mantra’s ritual credentials—metre, ṛṣi, and deity—and introduces nyāsa, the consecratory placement that sanctifies the practitioner and the act of worship before approaching the Linga.
By presenting siddhi as arising through properly consecrated practice under a presiding deity aligned to Shiva’s sphere (Skanda as a Shaiva power), it implies that attainments are granted by Pati (the Lord) when pasha is ritually and inwardly purified.
Mantra-nyāsa—placing the mantra’s power onto the body and limbs—linking external ritual to inner discipline, a preparatory step compatible with Shaiva/Pāśupata sādhanā.
