Context: As far as I recall, it's a question of the total dissolution of all notions of an other-worldly salvation. During those years this was going on in me all the time and being replaced by a sense of the holiness — to put it clumsily — to be found in man himself. The only holiness which really exists. A holiness wholly of this world. And I suppose that's what the final sequence tries to express. The notion of love as the only thinkable form of holiness.
At the same time another line of development in my idea of God begins here, one that has perhaps grown stronger over the years. The idea of the Christian God as something destructive and fantastically dangerous, something filled with risk for the human being and bringing out in him dark destructive forces instead of the opposite.

Lorsque les femmes nous aiment, elles nous pardonnent tout, même nos crimes; lorsqu'elles ne nous aiment pas, elles ne nous pardonnent rien, pas même nos vertus!
