Eckankar

Eckankar ( ) is an American new religious movement founded by Paul Twitchell in 1965. The group’s spiritual home is the Temple of ECK in Chanhassen, Minnesota. Eckankar is not affiliated with any other religious group.

The movement teaches simple spiritual exercises, such as singing "''HU''", called "a love song to God", to experience the "light" and "sound" of God and recognize the presence of the Holy Spirit. Provided by Wikipedia
