Truth shall set you free.

Truth is within ourselves it takes no rise
From outward things, whate’er you may believe.
There is an inmost centre in us all,
Where truth abides in fullness and around,
Wall upon wall, the gross flesh hems it in,
This perfect clear perception–which is truth.

A baffling and perverting carnal mesh
Binds it, and makes all error, and to know,
Rather consists in opening out a way
Whence the imprisoned splendour may escape,
Then in effecting entry for a light
Supposed to be without.

by Robert Browning “Paracelsus” Part 1
