Śakra–Namuci-saṃvāda: Śoka-nivāraṇa and Daiva-vicāra
Indra and Namuci on grief, composure, and inevitability
अविवेक, मोह, प्रमाद, स्वप्न और आलस्य--ये किसी तरह भी क्यों न हों, तमोगुणके ही विविध रूप हैं ।।
avivekaḥ mohaḥ pramādaḥ svapnaś ca ālasyaṃ ca—ete yathā-kathaṃcid api tamoguṇasyaiva vividha-rūpāṇi. atra yat prīti-saṃyukte kāye manasi vā bhavet, vartate sāttviko bhāva iti apekṣeta tat tathā; etat sattva-guṇa-vṛddhiṃ jānīyāt.
毗湿摩开示：缺乏辨别（aviveka）、迷妄（moha）、放逸（pramāda）、睡眠与懒惰——无论以何种形态出现——都只是昏暗之性 tamas（惰性、黑暗）的种种变相。相反，凡在身或心中生起、并与喜悦与内在满足相应的状态，应当视为 sāttvika（清净之性）的倾向；应知那是 sattva（明净、澄明之性）增长之相。

Educational Q&A
Bhishma classifies certain mental states—non-discrimination, delusion, heedlessness, sleepiness, and laziness—as expressions of tamas (inertia and obscuration). He then gives a practical marker of sattva: a wholesome gladness or inner contentment arising in body or mind indicates a sāttvika disposition and should be taken as growth of clarity and virtue.
In the Shanti Parva’s instruction to Yudhishthira, Bhishma continues his ethical-psychological teaching by distinguishing the guṇas through observable states of mind and behavior, helping the listener diagnose tamasic decline and recognize sattvic uplift.
