मनांसि तापयद्वंद्वं दीपयद्वितयं ततः । शोषयद्वितयं पश्चान्मारयद्वितयं ततः ॥ १४९ ॥
manāṃsi tāpayadvaṃdvaṃ dīpayadvitayaṃ tataḥ | śoṣayadvitayaṃ paścānmārayadvitayaṃ tataḥ || 149 ||
D’abord, la paire des contraires brûle les esprits; puis elle attise le double, comme deux feux. Ensuite elle dessèche le double, les deux appuis de la vie, et enfin elle anéantit le double, les deux souffles vitaux.
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.
