Adhyāya 164: Gautama as Guest; Kaśyapa’s Satkāra and the Fourfold Arthagati; Journey to Virūpākṣa
प्रीत्या शोक: प्रभवति वियोगात् तस्य देहिनः । यदा निरर्थकं वेत्ति तदा सद्यः प्रणश्यति
prītyā śokaḥ prabhavati viyogāt tasya dehinaḥ | yadā nirarthakaṃ vetti tadā sadyaḥ praṇaśyati ||
प्रीत्या शोकः प्रभवति वियोगात् तस्य देहिनः । यदा निरर्थकं वेत्ति तदा सद्यः प्रणश्यति ॥
भीष्म उवाच
Grief is born from affectionate attachment and separation; it subsides when one clearly recognizes its futility and lack of constructive outcome, cultivating discernment and steadiness of mind.
In the Śānti Parva’s instruction on right conduct and inner discipline, Bhīṣma teaches the listener that sorrow is a psychological effect of attachment to embodied beings and can be overcome through understanding and reflection.
