Shloka 4.18.55
वाली–रामसंवादः (Rama’s Justification to Vali on Rājadharma)
या ते नरपते वृत्तिर्भरते लक्ष्मणे च या।सुग्रीवे चाङ्गदे राजंस्तां त्वमाधातुमिहासि।।
yā te narapate vṛttir bharate lakṣmaṇe ca yā | sugrīve cāṅgade rājaṃs tāṃ tvam ādhātum ihārhasi ||
O lord of men, the same faithful regard you show to Bharata and to Lakshmana—O king—extend that very regard here to Sugriva and to Angada as well.
'O lord of men! may you have the same kind of affection for Sugriva and Angada as you have for Bharata and Lakshmana.
Dharma calls for impartial benevolence: those taken under one’s protection should receive care comparable to one’s own family.
Vali urges Rama to treat the Vanara king Sugriva and young Angada with the same steadfast concern Rama shows his own brothers.
Loyal, family-like commitment—Rama’s capacity to extend kinship ethics beyond blood relations.
