Nārāyaṇa-tejas: Kṛṣṇa’s Vrata, the Fire-Manifestation, and the Sages’ Inquiry (अनुशासन पर्व, अध्याय १२६)
यद् यद्धि किंचित् संधाय पुरुषस्तप्यते तप: । सर्वमेतदवाप्नोति विद्यया चेति न: श्रुतम्,“जो कोई भी उद्देश्य लेकर पुरुष तपस्यामें प्रवृत्त होता है, वह सब उसे तप और विद्यासे प्राप्त हो जाता है; यह हमारे सुननेमें आया है
yad yaddhi kiñcit sandhāya puruṣas tapyate tapaḥ | sarvam etad avāpnoti vidyayā ceti naḥ śrutam ||
Bhishma berkata: “Apa jua tujuan khusus yang ditetapkan seorang lelaki dalam hatinya lalu dia menempuh tapa untuknya, semuanya akan diperolehnya—demikianlah yang kami dengar—melalui kekuatan pengekangan diri yang berdisiplin dan melalui ilmu.”
भीष्म उवाच
A clearly formed intention (saṅkalpa) combined with tapas (disciplined self-restraint) and vidyā (knowledge) becomes a powerful means of attainment; the verse presents this as an established traditional teaching (śruti/received hearing).
In Anuśāsana Parva, Bhishma continues his didactic discourse on dharma and right conduct. Here he states a general principle: people who undertake austerity with a definite aim can achieve that aim through the combined efficacy of penance and knowledge.
