“There are no rules. However, principles may be discerned in actual practice; for example, in the way people actually speak, or in the lines the poets have written.”

The Paris Review interview
Context: Sylvia went furthest in the sense that her secret was most dangerous to her. She desperately needed to reveal it. You can’t overestimate her compulsion to write like that. She had to write those things — even against her most vital interests. She died before she knew what The Bell Jar and the Ariel poems were going to do to her life, but she had to get them out. She had to tell everybody... like those Native American groups who periodically told everything that was wrong and painful in their lives in the presence of the whole tribe. It was no good doing it in secret; it had to be done in front of everybody else. Maybe that’s why poets go to such lengths to get their poems published. It’s no good whispering them to a priest or a confessional. And it’s not for fame, because they go on doing it after they’ve learned what fame amounts to. No, until the revelation’s actually published, the poet feels no release. In all that, Sylvia was an extreme case, I think.

The Spiritual Message of Hazrat Inayat Khan
Context: Many people of various beliefs and faiths have written about the practice of the presence of God, and all speak of the happiness they receive from being in His presence. So it is no wonder that the Sufi also, should he wish to speak of it, should testify to similar happiness. He does not claim to a greater happiness than his fellow men because he is a human being and subject to all the shortcomings of mankind. But at the same time others can decide about his happiness better even than his words can tell it. The happiness which is experienced in God has no equal in anything in the world, however precious it may be, and everyone who experiences it will realize the same.
