ब्राह्मणस्य पूर्वतरा वृत्तिः — The Earlier Ideal Conduct of a Brahmana
River-of-Saṃsāra Metaphor
अयं स पुरुष: श्यामो लोकस्य दुरतिक्रम:
ayaṃ sa puruṣaḥ śyāmo lokasya duratikramaḥ
毗湿摩说道:“此人本身,形色黝黑,乃世间不可逾越者——一种不可超越、不可触犯的力量;在他面前,凡俗的界限与人间的尺度尽皆失效。”
भीष्म उवाच
The verse asserts the unsurpassable status of the ‘Puruṣa’: a reality so authoritative and foundational that the world cannot ‘cross’ or override him—implying that dharma and ethical order ultimately rest on a higher, inviolable principle.
In Śānti Parva’s instruction, Bhīṣma is describing a transcendent figure—identified by dark hue and by being ‘duratikrama’—to emphasize to the listener that there exists a supreme, unassailable ground of order beyond ordinary human power.
