अष्टत्रिंशन्मंत्ररूपा श्शिष्यदेहेऽथ मस्तके । समावाह्य शिवं मुद्राः स्थापनीयाः प्रदर्शयेत्
aṣṭatriṃśanmaṃtrarūpā śśiṣyadehe'tha mastake | samāvāhya śivaṃ mudrāḥ sthāpanīyāḥ pradarśayet
Having invoked Śiva, the teacher should demonstrate and then establish the mudrās—formed as thirty-eight mantra-embodiments—upon the disciple’s body, and especially upon the head.

It teaches that Śiva is invoked and sealed into the practitioner’s embodied awareness through mantra-formed mudrās, sanctifying the disciple’s body as a fit vessel for Śiva-sādhana and liberation-oriented discipline.
Just as the liṅga is ritually invoked (āvāhana) as Saguna Śiva for worship, the disciple’s body is also treated as a consecrated field where Śiva’s presence is installed through mantra and mudrā, aligning inner worship with outer liṅga-pūjā.
A dīkṣā-style practice of āvāhana followed by nyāsa-like placement of mudrās (energetic seals) on the body and head—used to stabilize mantra-power, protect the sādhaka, and focus meditation on Śiva.
