Yoga–Sāṃkhya Synthesis, Chariot Allegory, and the Vyakta–Avyakta Distinction
महतस्तपसो ्युष्ट्या पश्यँल्लोकौ परावरौ । सामान्यमृषिभिर्गत्वा ब्रह्मलोकनिवासिभि:
bhīṣma uvāca | mahatas tapaso 'nuṣṭhyā paśyan lokau parāvarau | sāmānyam ṛṣibhir gatvā brahmaloka-nivāsibhiḥ ||
毗湿摩说道：“他以大苦行之力，得以观见上界与下界。与居于梵天界（梵世界）的诸仙同列而行，他随心游历——其清净与苦行之威，使他得以遍观三界。”

Educational Q&A
The verse highlights that disciplined austerity (tapas) and purity can elevate a person’s spiritual capacity—granting broader vision of reality and enabling association with higher sages—implying that inner refinement, not birth or power, is the basis of true spiritual stature.
Bhishma begins a story about the sage Narada: through great tapas he gains the ability to perceive higher and lower realms and to move among the Brahmaloka-dwelling rishis, freely traversing the worlds by his spiritual attainment.
