Vimokṣa-niścaya: Pañcaśikha’s Analysis of Aggregates, Guṇas, and Tyāga (मोक्षनिर्णयः)
सम्मोहकं तमो विद्यात् कृष्णमज्ञानसम्भवम् | प्रीतिदुःखनिबद्धांश्व समस्तांस्त्रीनथो गुणान्
bhīṣma uvāca | sammohakaṃ tamo vidyāt kṛṣṇam ajñāna-sambhavam | prīti-duḥkha-nibaddhāṃś ca samastāṃs trīn atho guṇān |
ビーシュマは言った。「タマスとは迷妄をもたらす力であり、黒き闇のごとく、無知より生ずるものと知るべきである。すべての衆生を縛る三グナのうち、満足と愛着を生む傾向はサットヴァ的（サーットヴィカ）であり、苦を生む傾向はラジャス的（ラージャサ）である。かくして三グナの性質を見分けよ。」

Educational Q&A
Bhishma defines the ethical-psychological markers of the guṇas: tamas is delusion and darkness arising from ignorance; sattva is associated with clarity and pleasant, affectionate states; rajas is associated with agitation that culminates in suffering. The teaching urges discernment of these inner forces to guide conduct toward dharma.
In the Shanti Parva’s instruction on right living and inner discipline, Bhishma continues his counsel by classifying mental dispositions through the framework of the three guṇas, explaining how they manifest and how they bind beings.
