मृत्यु-काल-प्रबोधनम् (Instruction on Mortality, Time, and Truth) — Mahābhārata, Śānti-parva 169
आत्मानं पीडयित्वापि सुहृत्कार्यपरायणा: । विरज्यन्ति न मित्रेभ्यो वासो रक्तमिवाविकम्
ātmānaṃ pīḍayitvāpi suhṛt-kārya-parāyaṇāḥ | virajyanti na mitrebhyo vāso raktam ivāvikam ||
Disse Bhīṣma: Mesmo quando precisam afligir a si próprios, aqueles devotados a realizar o bem de um amigo não se afastam dos amigos—assim como um tecido de lã não perde a tintura que nele se entranhou.
भीष्म उवाच
True friends remain steadfast in loyalty and service to a friend’s good, even at personal cost; genuine attachment to virtuous friendship does not fade easily, like dye that holds fast in wool.
In Bhīṣma’s instruction in the Śānti Parva, he is describing the mark of noble character: unwavering commitment to a friend’s welfare, illustrated through a homely simile of dyed woollen cloth.
