Shloka 58
मनु-उपदेशः — भूत-उत्पत्ति, इन्द्रिय-निवृत्ति, तथा पर-स्वभाव-विवेकः
Manu’s Instruction on Elemental Origination, Sense-Withdrawal, and Discrimination of the Supreme Nature
न चात्मा शक््यते द्रष्टमिन्द्रियैश्न विभागश: । तत्र तत्र विसृष्टैश्न दुर्वार्यश्षाकृतात्मभि:
na cātmā śakyate draṣṭum indriyaiḥ na vibhāgaśaḥ | tatra tatra visṛṣṭaiḥ na durvāryaiḥ akṛtātmabhiḥ ||
毗湿摩说道：真我（Self）不能为诸根（感官）所直接见取，也不能被把握为可分割的部分之物。凡未能制御其心者——其感官被不可遏止地驱向外境，逐一追逐诸对象——终不能证得真我。

Educational Q&A
Self-realization is not a sensory achievement: the Ātman is beyond the reach of the outward-driven senses. Without self-mastery (especially restraint of the senses and mind), one cannot attain direct knowledge of the Self.
In the Śānti Parva’s instruction on dharma and liberation, Bhīṣma continues teaching about inner discipline. He explains to the listener that uncontrolled senses scatter toward objects and thereby obstruct the realization of the Ātman.
