The Description of the Four Durgā Mantras
आद्यं द्वितीयं करयोस्तार्तीयमुभयं न्यसेत् । मूलाधारे हृदि न्यस्य भूयो बीजत्रयं क्रमात् ॥ ४६ ॥
ādyaṃ dvitīyaṃ karayostārtīyamubhayaṃ nyaset | mūlādhāre hṛdi nyasya bhūyo bījatrayaṃ kramāt || 46 ||
He should place the first and the second seed-mantras upon the two hands, and the third upon both (hands together). Then, having placed them at the mūlādhāra and at the heart, he should again install the triad of seed-mantras in due order.

Vrata: none
Primary Rasa: shanta
Secondary Rasa: bhakti
It prescribes nyāsa—ritual installation of mantra-power—showing that inner worship is stabilized by placing seed-mantras in specific loci (hands, mūlādhāra, heart) and repeating them in a deliberate sequence.
Although technical, the method supports bhakti by sanctifying the body as an instrument of worship; ordered nyāsa helps the devotee concentrate the mind and offer mantra-japa with steadiness and reverence.
It highlights practical mantra-vidhi: kara-nyāsa (hand placement), internal nyāsa at mūlādhāra and hṛd (heart), and kramāt (precise sequencing), a hallmark of technical ritual instruction.
