The Description of the Four Durgā Mantras
मंत्रस्य सिद्ध्यै यतवाग्ध्यायन्देवीं निरंतरम् । सहस्रादूर्द्धूतः शत्रुर्ज्वरेण परिगृह्यते ॥ १६३ ॥
maṃtrasya siddhyai yatavāgdhyāyandevīṃ niraṃtaram | sahasrādūrddhūtaḥ śatrurjvareṇa parigṛhyate || 163 ||
മന്ത്രസിദ്ധിക്കായി വാക്ക് നിയന്ത്രിച്ച് ദേവിയെ നിരന്തരം ധ്യാനിക്കുന്നവൻ, ദൂരത്തേക്ക് തള്ളപ്പെട്ട ശത്രുവിനെയും ജ്വരം പിടിപ്പിക്കുന്നു.
Sanatkumara (in instruction to Narada on mantra-prayoga within technical disciplines)
Vrata: none
Primary Rasa: raudra
Secondary Rasa: bhayanaka
It links mantra-siddhi to inner discipline—especially vāg-niyama (restraint of speech) and uninterrupted dhyāna—showing that spiritual power is rooted in sustained focus and self-control.
Bhakti is expressed here as niraṃtara-upāsanā—continuous remembrance and meditation on Devī—implying that steady devotion is itself a means to attain efficacy in sacred practice.
It reflects technical mantra-prayoga: the sādhanā prerequisites (speech-restraint, continuous meditation) used in ritual/occult applications, aligning with the text’s Third Pada focus on disciplined methods within Vedic auxiliary sciences.
