सुस्थेयं क्षुधधारासु निशितासु महीपते । धारणासु तु योगस्य दुःस्थेयमकृतात्मभि:,पृथ्वीपते! छुरेकी तीखी धारपर कोई सुखपूर्वक खड़ा रह सकता है; किंतु जिनका चित्त शुद्ध नहीं है, ऐसे मनुष्योंका योगकी धारणाओंमें स्थिर रहना नितान्त कठिन है

su-stheyaṁ kṣudhā-dhārāsu niśitāsu mahīpate | dhāraṇāsu tu yogasya duḥstheyam akṛtātmabhiḥ pṛthvīpate ||

Bhīṣma said: “O king, one may stand with ease even upon the sharp edge of a blade; but for those whose inner self is unrefined and undisciplined, to remain steady in the practices of yogic concentration (dhāraṇā) is exceedingly difficult.”

Educational Q&A

External hardships can be borne, but true steadiness in yogic concentration demands an inwardly purified, disciplined mind; without self-mastery (kṛtātman), dhāraṇā becomes extremely difficult.

In the Śānti Parva’s instruction to the king, Bhīṣma emphasizes the rigor of inner spiritual practice, using the razor-edge image to contrast physical endurance with the greater challenge of mental and ethical self-discipline required for yoga.
