First at all i must say that is my fault that i didn't included the full credits, as you can see i always included it in ALL of my videos, but don't know why it didn't happen with this one, i don't made it intentional and is a pleasure for me to give the deserved credits to his authors.
You are focusing and killing me for just one error instead of giving me benefit of the doubt, please read the full description to understand what i made here since this is nothing about plagiarism.
Because i didn't know how yo edit the description (don't know why but i cant do it...) i will add here the original credits.
Credits:
Image have been provided by Andreas Lischka, the sound have been provided by Jesse Gallagher, both are free to use, I have been created this video thanks to his archives.
Descriptions belong to http://powerthoughtsmeditationclub.com/what-is-the-solfeggio-frequencies/ and https://www.yogapedia.com/definition/6533/trataka
ps: anyway i will try to re upload it with rhe deserved description.
