न विद्येते स मंत्रस्तु स्तंभितः सिद्धिरोधकृत् । अग्निः पवनसंयुक्तो मनोर्यस्य तु मूर्द्धनि ॥ २९ ॥
na vidyete sa maṃtrastu staṃbhitaḥ siddhirodhakṛt | agniḥ pavanasaṃyukto manoryasya tu mūrddhani || 29 ||
Mantra itu sesungguhnya tidak berfungsi; ia menjadi terhenti (stambhita) dan menghalangi pencapaian rohani (siddhi). Bagi orang yang di kepalanya api batin bersatu dengan angin (napas/prāṇa), pikirannya menjadi gelisah dan terhambat.
