The sight of a gate like this snags up bits of Gospel from chthonic waters of my mind, mostly Jesus-saids from the evangel Matthew,

Ask, and it shall be given you; seek, and ye shall find; knock, and it shall be opened unto you…

and,

Enter ye in at the strait gate: for wide is the gate, and broad is the way, that leadeth to destruction, and many there be which go in thereat: Because strait is the gate, and narrow is the way, which leadeth unto life, and few there be that find it.

There’s Blake with his Gates of Perception, which need to be cleansed, in order that every thing would appear as it is. Then there’s C.S. Lewis, the anti-Blake, who willingly believed…

…the damned are, in one sense, successful, rebels to the end; that the doors of hell are locked on the inside.
