Shloka 5.51.31
हनूमदुपदेशः रावणस्य च कोपः (Hanuman’s Counsel to Ravana and Ravana’s Wrath)
कामं खल्वहमप्येकस्सवाजिरथकुञ्जराम्।।।।लङ्कां नाशयितुं शक्तस्तस्यैष तु न निश्चयः।
kāmaṃ khalv aham apy ekaḥ savājirathakuñjarāṃ laṅkāṃ nāśayituṃ śaktaḥ; tasyaiṣa tu na niścayaḥ.
Even alone, I am indeed capable of destroying Laṅkā—teeming with horses, chariots, and elephants; yet this is not my resolve, for I have no such mandate.
" Alone, I can destroy this entire Lanka teeming with horses, chariots and elephants. Indeed I have the energy but not the mandate of Sri Rama.
Strength must be governed by duty and rightful authorization; even if one can act, dharma requires restraint when the action is not one’s rightful mandate.
Hanuman, having met Sita and revealed himself in Lanka, addresses Ravana with a warning—asserting his power but emphasizing he will not exceed Rama’s mission and command.
Maryādā (discipline within rightful limits) and self-control: Hanuman subordinates personal capability to Rama’s purpose.
