Adhyāya 26 — Ekākṣara-Brahman (“Om”) and the Hṛdayastha Guru
Inner Teacher
एतदेवेदृशं सूक्ष्मं ब्रह्मचर्य विदुर्बुधा: । विदित्वा चान्वपद्यन्त क्षेत्रज्ञेनानुदर्शिता:
etad evīdṛśaṃ sūkṣmaṃ brahmacaryaṃ vidur budhāḥ | viditvā cānvapadyanta kṣetrajñenānudarśitāḥ ||
智者了知：此正是梵行（brahmacarya）之微妙精髓。既已明了，又蒙“知田者”（kṣetrajña）开示引导，那些自知而觉醒之人便受持此道，恒常依之而住——坚定守护此等清净律仪。

Educational Q&A
True brahmacarya is described as a subtle, inward discipline recognized by the wise; when one is instructed by the kṣetrajña (the inner knower/self), one understands its real nature and steadily lives according to it.
A brāhmaṇa speaker is explaining the refined meaning of brahmacarya, emphasizing that awakened, self-knowing persons—after receiving right guidance—undertake and continually maintain this disciplined way of life.
