Mahāviṣṇu-Mantras: Aṣṭākṣarī, Sudarśana-Astra, Nyāsa Systems, Āvaraṇa-Pūjā, and Prayogas
मनांसि तापयद्वंद्वं दीपयद्वितयं ततः । शोषयद्वितयं पश्चान्मारयद्वितयं ततः ॥ १४९ ॥
manāṃsi tāpayadvaṃdvaṃ dīpayadvitayaṃ tataḥ | śoṣayadvitayaṃ paścānmārayadvitayaṃ tataḥ || 149 ||
మొదట ద్వంద్వయుగం మనస్సులను దహింపజేస్తుంది; తరువాత ద్వివిధ అగ్నులను ప్రదీప్తం చేస్తుంది. ఆపై ద్వివిధ ఆధారాలను శోషిస్తుంది, చివరికి ద్వివిధ ప్రాణశక్తులను నశింపజేస్తుంది॥१४९॥
Narada (continuing a technical exposition in Book 1.3)
Vrata: none
Primary Rasa: raudra
Secondary Rasa: bhayanaka
It maps a step-by-step inner decline: when one is ruled by dvandva (dualities), the mind is first agitated, then inner energies flare up, the body-mind system dries out, and finally the life-supporting forces collapse—urging mastery over dualistic reactions.
By implying that steady devotion to the Lord stabilizes the mind beyond dualities (pleasure/pain, gain/loss). Bhakti functions as an antidote to dvandva, preventing the chain-reaction that ends in spiritual and vital ruin.
The verse uses a sutra-like, technical enumeration (a common Vedanga-style pedagogic method) to classify effects in pairs (vitayaṃ), helping students remember causal sequences—useful for disciplined study and applied spiritual practice.
