"You cannot know the knower, for you are the knower. The fact of knowing proves the knower. You need no other proof, The knower of the known is not knowable. Just like light is known in colours only, so is the knower known in knowledge." Sri Nisargadatta Maharaj

When when is no more

simplicity 

is

the core

The gateless gate is boundlessly open

The stateless state is timelessly here

You are That

Clear understanding

is 

glowing

as the silent knowing
