I'm handing you the keys

I'm handing you the keys
to the gate to the way of truth

Three times two they are,
and then their eye at last.

First these two, who and what,
I think you will find useful, 
in pointing at correctness.

The I'll give you how and why,
to give them life.

Thence when and where.
Now they are affixed.
Too affixed.

For how to search, if you can't
ask an if.
