सार्द्धद्वादशवर्णो वा धूमितो र्निदितस्तु सः । सार्द्धबीजत्रययुतो मंत्रो विंशतिवर्णवान् ॥ ४६ ॥
sārddhadvādaśavarṇo vā dhūmito rniditastu saḥ | sārddhabījatrayayuto maṃtro viṃśativarṇavān || 46 ||
Thần chú ấy, nếu gồm mười hai rưỡi âm tiết, thì được gọi là “Dhūmita” và bị chê trách. Nhưng khi được trang bị ba rưỡi bīja, thần chú trở thành thần chú hai mươi âm tiết.

It stresses that mantra efficacy depends on correct mantra-lakṣaṇa—especially syllable-count and proper inclusion of bījas—so that practice is aligned with śāstric phonetics and ritual science rather than arbitrary recitation.
Bhakti is supported by disciplined sādhana: the verse implies devotion should be expressed through properly formed mantra-japa, where correct sound-structure (varṇa) safeguards the intended devotional focus and results.
Śikṣā (Vedic phonetics) and mantra-śāstra: the verse gives a technical rule about mantra syllable-counts and how adding bīja-syllables changes the mantra’s measured length and acceptability.
