"The deep longing for redemption and release - consciously from ‘sins’, unconsciously from sexual tensions - is warded off. States of religious ecstasy are nothing other than conditions of sexual excitation of the vegetative nervous system, which can never be released. Religious excitation cannot be comprehended and therefore cannot be mastered, without first understanding the contradiction by which it is ruled. It is not only anti- sexual, but to a large extent sexual as well. It is not only moralistic; it is altogether unnatural. From a sex-economic point of view, it is unhygienic."
