Adhyāya 26 — Ekākṣara-Brahman (“Om”) and the Hṛdayastha Guru
Inner Teacher
तस्य चानुमते कर्म ततः पश्चात् प्रवर्तते । गुरुर्बोद्धा च श्रोता च द्वेष्ट च हृदि निःसृत:
tasya cānumate karma tataḥ paścāt pravartate | gurur boddhā ca śrotā ca dveṣṭā ca hṛdi niḥsṛtaḥ |
その御許しによってのみ行為は是認され、ついで有身の生命（ジーヴァ）はまさにその行為へと駆り立てられる。ゆえに、心臓の内より顕れる至上我こそ、師であり、知者であり、聞き手であり、また退ける者でもある。
ब्राह्मण उवाच
Educational Q&A
Action is not merely a personal impulse; it is portrayed as proceeding after the assent of the indwelling Supreme Self. The verse frames the inner Self as the ultimate moral and cognitive authority—teacher, knower, hearer, and the one who disapproves—thereby grounding ethical discernment in an inner divine witness.
A Brahmin speaker explains a doctrine of inner governance: the jīva’s engagement in action follows an inner approval, and the presence within the heart is described in multiple roles (guru, knower, hearer, rejecter) to show how guidance and restraint arise from within.
