Mahabharata — Anushasana Parva, Shloka 73
तत्परेणैव नान्येन शक््यं होतस्य दर्शनम् । किंतु वे बालक हैं। अहंकारवश अपनेको पण्डित मानते हैं। अतः वे जो पूर्वोक्त निश्चय करते हैं
tatpareṇaiva nānyena śakyaṃ hotasya darśanam |
毗湿摩说道：对那至上实相的证见，除了一心专注于它之外，别无他途。唯有舍弃懈怠，长久修习瑜伽，并不断奋求亲证者，方能见此真理；其余皆不能。仅凭感官之见不足以裁定真实——正如天空之蓝虽显现于目前，终究却是幻相。因此，在法、神与来世等事上，经论圣典之证言为最高权威，因为其他认知手段不能抵达彼境。若问：唯一的梵（Brahman）何以能为世界之因？答曰：以持久的瑜伽纪律与不息的求证之功，同时负责任地维持此身之行住，求道者终将获得直接洞见。

Educational Q&A
Direct realization of the supreme truth is possible only through sustained, single-minded spiritual discipline (yoga) and persistent effort; sense-perception alone cannot adjudicate realities beyond its reach, so śāstra is authoritative regarding dharma, God, and the afterlife.
Bhīṣma instructs the listener by critiquing overconfidence in mere perception and intellectual pride, using the example of the sky’s apparent blueness to show perceptual error, and then prescribing long-term yogic practice and steady striving as the means to ‘see’ Brahman.
