nāhaṁ manye suvedeti no na vedeti veda ca
nāhaṁ manye suvedeti no na vedeti veda ca |
yo nas tad veda tad veda no na vedeti veda ca ||
(Kena Upaniṣad: 2.2)
“I do not think that I know well, nor do I not know [at all]. I also know [somewhat]. Who among us [thinks that he] knows that [viz., Brahman] does not know that, and one who [thinks that he] does not know [Brahman] knows.”
