मृत्यु-काल-प्रबोधनम् (Instruction on Mortality, Time, and Truth) — Mahābhārata, Śānti-parva 169
ये च दोषसमायुक्ता नराः प्रोक्ता मयानघ
bhīṣma uvāca | ye ca doṣa-samāyuktā narāḥ proktā mayānagha, niṣpāpa nareśa! teṣāṃ sarveṣām adhamo bhavati kṛtaghnaḥ | sa mitra-vadhyam api karoti | tādṛśān durācārān narādhamān dūrata eva tyajet | eṣa sarveṣāṃ niścayaḥ |
ພີສະມະກ່າວວ່າ: «ໂອ ພະຣາຊາຜູ້ບໍ່ມີມົນທິນ, ໃນບັນດາຄົນທີ່ຂ້າໄດ້ກ່າວວ່າມີຄວາມດ່າງພ້ອຍນັ້ນ, ຜູ້ຕໍ່າສຸດແມ່ນຜູ້ອະກະຕັນຍູ. ຄົນເຊັ່ນນັ້ນອາດກ້າໄປເຖິງຂັ້ນຂ້າມິດຂອງຕົນເອງ. ດັ່ງນັ້ນ ຄົນຊົ່ວຜູ້ປະພຶດຊົ່ວເຫຼົ່ານັ້ນ ຄວນຖືກລະທິ້ງແຕ່ໄກ. ນີ້ແມ່ນຄວາມເຫັນພ້ອມອັນໝັ້ນຄົງຂອງທຸກຄົນ».
भीष्म उवाच
Gratitude is a foundational virtue in dharma; ingratitude (kṛtaghnatā) marks the lowest character because it can drive a person to betray and even destroy benefactors and friends. Such people should be avoided decisively.
In Bhishma’s instruction to the king during the Śānti Parva, he classifies moral faults and singles out the ungrateful person as the worst, advising the ruler to keep distance from such corrupt individuals for personal and social safety.
