Total Bullshit. As far as you can see everything has it's contrary.
left-right
under-above
black-white and so on.

What about the sun. Sun gives light and sends energies.

The contrary is a black hole.

Never forget this again. Life is possible because these two are each others contrarys. One gives, one takes. 2 together(sun, black hole) makes life(3) possible. Hopefully everyone now understands the holy 3.

Youre left side is the conrary of you right side. These 2 makes your body(life) possible.

think about voltage. A - pole and a + pole. These to makes the existence of " life"every machine possible.
