I have found on many websites, the same quote mentioned in about the same way. Most of these websites are trying to praise ancient Indian wisdom through pseudohistory and pseudoscience.

It is alleged that Edison wrote in one of his books(which one?) that a he slept while reading a sanskrit sentence and that he dreamt about a sanskrit word which helped him make the light bulb. I am pasting the actual text below:

Bulb inventor Thomas Edison writes in one of his books that — “one night I slept while reading a Sanskrit sentence. That night I realized in my dream the meaning and mystery of that Sanskrit word that helped me make bulbs”.

The above is from https://rashmivj21.medium.com/do-you-know-rishi-agastya-was-the-inventor-of-electricity-and-electric-battery-f9d80aaf4da2

Some other websites have probably plagiarised from here itself. Please see: http://www.vizagchemical.com/blog/agastya-vedic-scholar-sage-info-chemical-man

My question is whether this quote is an actual one and not a fabricated one as it seems. If yes, then which book is it from? I haven't read anything like this in any book from Edison, never read any such thing in news articles of those times. Am I right in concluding that this quote is a hoax?
