The Description of the Four Durgā Mantras
सोष्णीषकंचुको विद्वान्कृष्णे भूते दिवानिशम् । उपवासी श्मशाने वा विपिने शून्यमंदिरे ॥ १६२ ॥
soṣṇīṣakaṃcuko vidvānkṛṣṇe bhūte divāniśam | upavāsī śmaśāne vā vipine śūnyamaṃdire || 162 ||
Bậc học giả, đội khăn và khoác áo choàng, vào ngày hắc nguyệt gọi là Kṛṣṇā-bhūtā, nên giữ trai giới suốt ngày đêm—dù ở bãi hỏa táng, trong rừng, hay nơi đền miếu vắng không.
Narada (teaching in a Vedanga/vrata context; dialogue tradition with Sanatkumara lineage implied for this section)
Vrata: none
Primary Rasa: bhayanaka
Secondary Rasa: shanta
It prescribes a severe vrata: sustained fasting through day and night in liminal places (cremation ground, forest, deserted shrine), emphasizing fearlessness, detachment, and disciplined ritual resolve.
While stated as an austerity rule, the underlying bhakti principle is single-pointed dedication—choosing restraint and sacred intent over comfort, which supports steadiness of mind for worship and remembrance.
It reflects tithi-based observance (time-discipline) and vrata procedure—how to structure an upavāsa across day and night and the prescribed setting—typical of technical dharma guidance aligned with Vedanga-style calendrical and ritual regulation.
