प्रस्रवणगिरिवासवर्णनम् (Residence on Mount Prasravana; Counsel during the Rains)
समुन्मूलय शोकं त्वं व्यवसायं स्थिरं कुरु।ततस्सपरिवारं तं निर्मूलं कुरु राक्षसम्।।4.27.37।।
na hy avyavasitaś śatruṃ rākṣasaṃ taṃ viśeṣataḥ | samarthas tvaṃ raṇe hantuṃ vikramair jihmakāriṇam || 4.27.36 ||
For without firm resolve, you will not be able to slay that enemy in battle—especially that rākṣasa—who acts with crooked stratagems, even with all your valor.
'Root out sorrow. Be daring. Be firm in resolve. (Only) then can you destroy the demon and his family.
Dharma in conflict requires disciplined resolve; moral purpose must be matched by steady effort to confront deceit and injustice.
Lakṣmaṇa argues that mere bravery is insufficient against a cunning foe like the rākṣasa king; Rāma must regain determination.
Vyavasāya (resolute enterprise): sustained, intelligent action rather than emotional collapse.
