पुष्पकविमानेन सीताया युद्धभूमिदर्शनम् (Sita Shown the Battlefield in the Pushpaka)
अद्यकालवशंप्राप्तंरणेरामंसलक्ष्मणम् ।अवेक्ष्यविनिवृत्तासाचान्यांगतिमपश्यती ।।।।निरपेक्षाविशालाक्षीमामुपस्थास्यतेस्वयम् ।
adyakālavaśaṃ prāptaṃ raṇe rāmaṃ salakṣmaṇam | avekṣya vinivṛttā sā cānyāṃ gatim apaśyatī | nirapekṣā viśālākṣī mām upasthāsyate svayam ||
Rāvaṇa reasoned: “In time, when the wide-eyed Sītā sees Rāma in battle together with Lakṣmaṇa brought under the power of fate, she will turn back; finding no other refuge, she will abandon hope and come to me of her own accord.”
Ravana thought that the broad eyed Sita coming to conclusion in course of time that Rama has gone along with Lakshmana, rid of hope, with no other haven, will seek him on her own accord.
The verse highlights adharma through coercive desire: Rāvaṇa imagines that despair will force Sītā to submit, contrasting with dharma where consent, restraint, and truthfulness are essential.
Rāvaṇa anticipates that if Sītā believes Rāma and Lakṣmaṇa are overcome in battle, she will lose hope and come to him; this sets up the deception that follows.
By contrast (implicitly), Sītā’s steadfast fidelity is the virtue; Rāvaṇa’s mindset shows the vice of delusion and unethical manipulation.
