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.
ଅବିବେକ, ମୋହ, ପ୍ରମାଦ, ସ୍ୱପ୍ନ ଓ ଆଳସ୍ୟ—ଯେପରି ଭାବେ ପ୍ରକଟ ହେଉନାହିଁ—ସବୁ ତମୋଗୁଣର ନାନା ରୂପ ମାତ୍ର। କିନ୍ତୁ ଶରୀର କିମ୍ବା ମନରେ ପ୍ରୀତି ଓ ଅନ୍ତଃସନ୍ତୋଷ ସହ ଯେ ଭାବ ଉଦିତ ହୁଏ, ତାହାକୁ ସାତ୍ତ୍ୱିକ ଭାବ ଭାବେ ଗ୍ରହଣ କରିବା ଉଚିତ; ଏହା ସତ୍ତ୍ୱଗୁଣର ବୃଦ୍ଧି ବୋଲି ଜାଣିବା ଉଚିତ।
भीष्म उवाच
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.
