A "sin" is something which is not necessary.
G. I. Gurdjieff

A man will renounce any pleasures you like but he will not give up his suffering.
G. I. Gurdjieff

Every ceremony or rite has a value if it is performed without alteration. A ceremony is a book in which a great deal is written. Anyone who understands can read it. One rite often contains more than a hundred books.
G. I. Gurdjieff

If you want to lose your faith, make friends with a priest.
G. I. Gurdjieff

In properly organized groups no faith is required; what is required is simply a little trust and even that only for a little while, for the sooner a man begins to verify all he hears the better it is for him.
G. I. Gurdjieff

It is the greatest mistake to think that man is always one and the same. A man is never the same for long. He is continually changing. He seldom remains the same even for half an hour.
G. I. Gurdjieff

Religion is doing; a man does not merely think his religion or feel it, he "lives" his religion as much as he is able, otherwise it is not religion but fantasy or philosophy.
G. I. Gurdjieff

Without self knowledge, without understanding the working and functions of his machine, man cannot be free, he cannot govern himself and he will always remain a slave.
G. I. Gurdjieff
