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 |
毗湿摩说：当知怛摩（tamas）为使人迷乱之力，黑暗如墨，生于无明。在束缚一切众生的三德之中，能生满足与爱悦之倾向为萨埵（sāttvika）；能生痛苦之倾向为罗阇（rājasa）。如是当辨明三德之性。

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.
