Bhīmasena’s Counsel on Grief, Inner Conflict, and the Duty of Kingship (भीमसेन-उपदेशः)
सत्त्वं रजस्तम इति मानसाः: स्युस्त्रयो गुणा: । तेषां गुणानां साम्य॑ं यत्तदाहु: स्वस्थलक्षणम्
sattvaṃ rajastama iti mānasāḥ syus trayo guṇāḥ | teṣāṃ guṇānāṃ sāmyam yat tad āhuḥ svasthalakṣaṇam ||
毗舍波耶那说道:“萨埵(sattva)、罗阇(rajas)与昏暗(tamas)乃心之三德。三德若能均衡相持,此等平衡之境,即被宣称为心神安泰之标志。”
वैशम्पायन उवाच
Mental well-being is defined as sāmyam—an inner equilibrium of the three guṇas (sattva, rajas, tamas). Health is not the absence of all impulses, but a balanced, well-governed mind.
In the didactic discourse of Śānti Parva, Vaiśampāyana continues explaining principles of inner discipline and right living, here characterizing mental health through the classical framework of the three guṇas.
