never will he abandon his resolution, who has acquired his merit by a long course of
actions through unnumbered aeons.

aprāpya notthāsyati tattvameṣa tamāsyahatveva sahasraraśmiḥ || 13.59
59. ‘Such is that purpose of his, that heroic effort, that glorious strength, that
compassion for all beings, — until he attains the highest wisdom, he will never rise
from his seat, just as the sun does not rise, without dispelling the darkness.
kāṣṭha hi mathnan labhate hutāśa bhūmi khanan vidati cāpi toyam |
nirbadhinaḥ kica na nāsya sādhya nyāyena yukta ca kta ca sarvam ||

60. ‘One who rubs the two pieces of wood obtains the fire, one who digs the earth
finds at last the water, — and to him in his perseverance there is nothing unattainable,
— all things to him are reasonable and possible.

mahābhiṣagnārhati vighnameṣa jñānauṣadhārtha parikhidyamānaḥ || 13.61

sa daiśikaḥ kṣobhayitu na yukta sudeśikaḥ sārtha iva pranaṣṭe || 13.62
62. ‘He who toilsomely pursues the one good path, when all the world is carried away
in devious tracks, — he the guide should not be disturbed, like a right informant when
the caravan has lost its way.

āryasya nirvāpayitu na sādhu prajvālyamānastamasīva dīpaḥ || 13.63
63. ‘He who is made a lamp of knowledge when all beings are lost in the great
darkness, — it is not for a right-minded soul to try to quench him, — like a lamp
kindled in the gloom of night.

yaścedamuttārayitu pravttaḥ kaścinnayettasya tu pāpamāryaḥ || 13.64
64. ‘He who, when he beholds the world drowned in the great flood of existence and
unable to reach the further shore, strives to bring them safely across, — would any
right-minded soul offer him wrong?
