अष्टादशः सर्गः (Sarga 18): रावणस्य प्रमदावनप्रवेशः — Ravana’s entry into the women’s grove
षडङ्गवेदविदुषां क्रतुप्रवरयाजिनाम्।शुश्राव ब्रह्मघोषांश्च स विरात्रे ब्रह्मरक्षसाम्।।5.18.2।।
sa ca kāma-parādhīnaḥ patis tāsāṁ mahābalaḥ |
sītā-sakta-manā mando mandāñcita-gatir babhau ||5.18.19||
And their husband—mighty though he was—appeared dulled, enslaved by desire, his mind fixed on Sītā, moving slowly with measured steps.
At dawn sounds of recitation of Vedas and the six auxillary sciences, (i.e .grammar, prosody, etymology, phonetics, astronomy and the science of rituals) by the brahmins among demons well-versed in performing exalted sacrificial ceremonies were heard.
It teaches that power without self-mastery collapses into weakness; dharma requires control over desire, while obsession leads away from satya and right judgment.
Rāvaṇa is portrayed in motion, yet psychologically impaired—preoccupied with Sītā and governed by passion.
The highlighted (by contrast) virtue is self-control; the epic frames uncontrolled kāma as a cause of downfall.
