Dīkṣā, Mantra-Types, Mantra-Doṣas, and Qualifications of Ācārya–Śiṣya
त्रस्तः स मंत्रो विज्ञेयो मुखे तारविवर्जितः । हकारः शक्तिरथवा भीतो मंत्रः स एव हि ॥ ३१ ॥
trastaḥ sa maṃtro vijñeyo mukhe tāravivarjitaḥ | hakāraḥ śaktirathavā bhīto maṃtraḥ sa eva hi || 31 ||
মুখে জপ কৰোঁতে ‘তাৰ’—প্ৰণৱ ‘ওঁ’—বিহীন যি মন্ত্ৰ, তাক ‘ত্ৰস্ত’ (ভীত) মন্ত্ৰ বুলি জানিব লাগে। তেতিয়া ‘হ’কাৰেই তাৰ শক্তি; সেই মন্ত্ৰই ‘ভীত’ নামে পৰিচিত।

It teaches that mantras are not merely words; their spiritual efficacy depends on correct traditional components—especially the praṇava (tāra, ‘Oṁ’)—and proper phonetic power (śakti) in recitation.
Bhakti is supported by disciplined practice: reverent, accurate chanting. The verse implies that devotion expressed through mantra should follow śāstric recitation rules so the offering of sound is complete.
Śikṣā (Vedic phonetics): it highlights the role of the praṇava/tāra in mantra-ucchāraṇa (chanting) and the idea of bīja-like phonetic power (e.g., hakāra) as mantra-śakti.
