What truth

What truth am I talking about?
I am talking about truth
Of the ground of mind,
Which can enter into the
Ordinary and the sacred,
Into the pure and the polluted,
Into the absolute and the conventional,
And yet is not the absolute,
Conventional, ordinary, and sacred,
But is able to give names
To all the absolute, conventional,
Ordinary, and sacred.
Someone who has realized this
Cannot be labeled by the
Absolute or the conventional,
By the ordinary or sacred.
If you can grasp it,
Then use it, without labeling it any more.
This is called the mystic teaching.
