I apologize for the length of this. I had intended a single post but, at over 4600 words, it is clearly much too long, so it will now be in three parts. (My target length is 1500 words per post.) Please postpone comments until the end, except for Ramesam to confirm or deny that my AI-assisted summary of his understanding is essentially correct).

In his series ‘Quintessence of 10 Upanishads’, Ramesam has used the word ‘knowingness’ quite a few times. For example, in Part 27 (Taittirīya Part 2), it occurs 11 times and, in Part 30 (Aitareya Part 1), 25 times!

On 5^th Aug, I made the following comment on Part 3 of the Aitareya series (https://www.advaita-vision.org/quintessence-of-10-upanishads-32-aita-3/):

I also see that you have used the word ‘knowingness’ again. When I read your first post, on Aitareya, I began my search to find our previous discussions about this (to me meaningless) word. Unfortunately, I could not immediately locate it and have embarked upon a long process of building a local AI to help me to track it down. As soon as I do so, I will aim to generate a separate post to talk about it.
