Adhyāya 51: Kṛṣṇa’s Leave-Taking and Departure for Dvārakā (द्वारकागमनानुमति)
निर्मुक्त: सर्वपापेभ्य: सर्व सृजति निष्कलम् | क्षेत्रज्ञ इति तं विद्याद् यस्तं वेद स वेदवित्
nirmuktaḥ sarvapāpebhyaḥ sarvaṃ sṛjati niṣkalam | kṣetrajña iti taṃ vidyād yas taṃ veda sa vedavit ||
जो सब पापों से मुक्त होकर भी निष्कलंक रहते हुए सबकी सृष्टि करता है, उसे ‘क्षेत्रज्ञ’ जानना चाहिए; जो उसे जान लेता है, वही वेदवेत्ता है।
वायुदेव उवाच
True spiritual knowledge is to recognize the kṣetrajña—the inner witness/knower—who remains pure and untouched while being the source through which the world of experience arises; knowing this principle is presented as the mark of real Vedic wisdom.
Vāyudeva is speaking in a didactic mode, defining a profound metaphysical principle: the untainted knower (kṣetrajña) who is free from sin and yet is associated with the origination of all things, and he declares that one who understands this is truly a ‘vedavit’.
