ब्राह्मणस्य पूर्वतरा वृत्तिः — The Earlier Ideal Conduct of a Brahmana
River-of-Saṃsāra Metaphor
यदा हि शोचत: शोको व्यसन नापकर्षति
yadā hi śocataḥ śoko vyasanaṁ nāpakarṣati
Bhīṣma said: When a person is grieving, grief does not remove the calamity; mere lamentation cannot undo misfortune. Therefore one should turn from sorrow to steadiness of mind and right action, for endurance and discernment are the proper response to adversity.
भीष्म उवाच
Grief by itself does not lessen or remove misfortune; one should move from lamentation to composure, discernment, and dharmic action as the effective way to face adversity.
In Śānti Parva, Bhīṣma instructs Yudhiṣṭhira on righteous conduct and mental discipline after the war; here he emphasizes that sorrow is unproductive unless transformed into steadiness and wise effort.
