Adhyāya 51: Kṛṣṇa’s Leave-Taking and Departure for Dvārakā (द्वारकागमनानुमति)
तपसश्चानुपूव्येंण फलमूलाशिनस्तथा । त्रैलोक्यं तपसा सिद्धा: पश्यन्तीह समाहिता:
tapasas cānupūrvyena phalamūlāśinas tathā | trailokyaṃ tapasā siddhāḥ paśyantīha samāhitāḥ ||
तपसश्चानुपूर्व्येण फलमूलाशिनस्तथा । त्रैलोक्यं तपसा सिद्धाः पश्यन्तीह समाहिताः ॥
वायुदेव उवाच
True higher perception arises from disciplined tapas practiced gradually, supported by simplicity (such as a fruits-and-roots diet) and sustained mental concentration; spiritual knowledge is presented as the fruit of ethical self-restraint and inner steadiness.
Vāyu explains how perfected sages, through sequential austerities and a restrained ascetic lifestyle, become samāhita (mentally collected) and thereby gain direct insight into the three worlds, describing the mechanism of spiritual accomplishment rather than a physical journey.
