Is Sufism a religion?
from the Teachings of Hazrat Inayat Khan

If anybody asks you, "What is Sufism? What religion is it?" you may answer, "Sufism is the religion of the heart, the religion in which one thing is most important, and that is to seek God in the heart of mankind."

There cannot be two religions, there is always one religion only and there cannot be a new one, as Solomon said that there is nothing new under the sun. Whenever the message of love and wisdom is given it is not a new religion, it is the revivification of religion, in order to bring to man the realization of the truth of the religion he follows. Sufism therefore does not bring a new religion, it brings that life and light which are necessary to revivify that religion that has always existed.

Sufism is only a light thrown upon one's own religion like a light brought into a room where everything one wants is to be found, and where the only thing that was needed was light.

Sufism is not a religion, for it is beyond the limitations of faiths and beliefs which make the diversity of religions in the world. Sufism, in short, is a change of outlook on life. It is like viewing from an aeroplane a town, the streets of which one has known and walked through, and yet one has never before seen the whole town at a glance. The Sufi's idea is to view life by raising himself above it.
