"3,6,9" The Secret Of The Universe:

Nikola Tesla is alleged to have stated: “If you only knew the magnificence of the 3, 6, and 9, then you would have a key to the universe.”

Why is 369 the key to the universe?

3, 6, and 9 are numbers that represent energy beyond what we can perceive with our five senses. 3, 6, 9 = Energy, Frequency, and Vibration. The Universe revolves around Energy, Frequency, and Vibration. 3, 6, and 9 also revolve around the Universe.

lthough it's uncertain whether the great inventor actually uttered the famous quote, there's no question he was indeed obsessed by the numbers.
