From a letter written by the avant-garde filmmaker Jonas Mekas to his peer and friend Stan Brakhage in April 1966. It is included in the anthology Letters as Films, edited by Garbiñe Ortega, which will be published this month by La Fábrica.

Dear Stan:

I am thinking.
I am still thinking.
God, why do I make so many mistakes! Because I am thinking? Probably, badly thinking.
Love to all.
The trees in the park are all white.
Some day . . .
I still do not know how to pray.

Love

Jonas
