"“The light is the left hand of darkness” "

No, it isn't.

Are you saying darkness is the body, and light is the left hand? So what's the right hand? More darkness?

Darkness doesn't exist. Light does. You can't measure 'speed of darkness', you can only measure speed of things that actually exist. The word 'darkness' only exists because it's practical, but in actual reality, darkness is nothing but LACK of light. That's all it is (so it isn't really anything).

Therefore, it's not only completely absurd to claim that light is somehow sub-genre of darkness, or that darkness somehow gives birth to light, when it's completely wrong.

You can have a house full of darkness, and open the doors and windows to a well-lit world - the darkness won't pour out, light pours in.

You can have a house full of light in a world surrounded by darkness, and open the doors and windows - darkness won't pour in, light pours out.

These are not metaphors, they're examples of how real life and reality work. Light is always something, and it always removes darkness, it's always 'stronger than darkness', because darkness doesn't really exist. In real terms, darkness is just 'perceived small amount of light'.

Light always exists, as the spirit that forms the Universe is fundamentally light. No matter how tiny amount it is, there's always some light, even if only on higher levels, like etheric or astral planes.

So any darkness is always just lack of light, and thus, doesn't exist as its own thing at all. Bring any light, and the darkness goes away. There's no big enough darkness to make the smallest candle in the world lightless.
