Dīkṣā, Mantra-Types, Mantra-Doṣas, and Qualifications of Ācārya–Śiṣya
मनोर्यस्यादिमध्यांते भूबीजद्वयमुच्यते । स तु रुद्धो मनुज्ञेयो ह्यतिक्लेशेन सिद्धिदः ॥ २२ ॥

ஆதி, நடு, முடிவில் ‘பூ’ எனும் இரு பீஜங்கள் கூறப்படும் மந்திரம்—அது கட்டுப்பாட்டுடன் (ருத்தமாக) காக்கப்பட்டால் ‘மனு’ என அறியப்பட வேண்டும்; அது மிகுந்த முயற்சி-தவத்தால் சித்தியை அளிக்கும்।
Sanatkumara (teaching Narada in a technical/Vedanga context)
Vrata: none
Primary Rasa: shanta
Secondary Rasa: bhakti
It teaches that mantra-power is not merely recitation; when the mantra is properly restrained/guarded (ruddha)—i.e., practiced with discipline, secrecy, and control—it becomes a true ‘manu’ (effective mantra) that yields siddhi, though only through sustained austerity.
While the verse is technical, it supports Bhakti by stressing disciplined practice: devotion becomes potent when paired with regulated sadhana (control of speech and mind), making the mantra a focused offering rather than casual utterance.
It highlights a Vedanga-style technical rule about mantra structure using bīja syllables (‘bhū’) and the method of ‘restraint’ (ruddha)—a practice aligned with śikṣā (phonetics) and mantra-vidhi (procedural discipline) for achieving mantra-siddhi.
