4.1.155

ataḥ paraṃ brahmabhūto bhūtātmā nopalabhyate/
niḥsṛtaḥ sarvabhāvebhyaścihnaṃ yasya na vidyate//
/ (gatirbrahmavidāṃ brahma taccākṣaramalakṣaṇam)(by gaṅgādhara ed.)/
jñānaṃ brahmavidāṃ cātra nājñastajjñātumarhati//

Beyond this, the individual self, having become Brahman, is not apprehended; / it has emerged from all states of existence, and no mark of it is found. / [The goal of the knowers of Brahman is Brahman, and that is imperishable and without mark;] / and the knowledge of the knowers of Brahman is here: an ignorant person is not fit to know it.
