369 Theory of Nikola Tesla

 One of the greatest Theories, Nikola Tesla was a genius scientist and very much obsessed with the numbers 3, 6, and 9. Why would he not be so? The 3- and 9-fold symmetries of nature, 360° in a circle, and the need of 21 days say it all.

From the spiritual point of view, the chanting of mantras is done 108 times.

All these numbers are divisible by  3.
