Canto 3 -
Araṇya-kāṇḍa
Chapter 40: Rāvaṇa Criticizes Mārīca
Text 3.40.18

प्रलोभयित्वा वैदेहीं यथेष्टं गन्तुमर्हसि॥

pralobhayitvā vaidehīṁ yatheṣṭaṁ gantum arhasi

pralobhayitvā = just allure; vaidehīm = Vaidehī; yathā-iṣṭam = as you like; gantum arhasi = and wander about.

Just allure Vaidehī and wander about as you like.

Rāvaṇa states why [Mārīca should do so] in the next verse.1

1 Rāmāyaṇa-bhūṣaṇa: kiṁ tasya prayojanaṁ tatrāha tvām iti.
