Eckankar
Eckankar (meaning Co-worker with God) is a modern-day religion, founded by Paul Twitchell in 1965. It is a non-profit religious group with members in over one hundred countries. The spiritual home is the Temple of ECK in Chanhassen, Minnesota.
Eckankar is not affiliated with any other religious group. Followers believe its purpose is to help individuals find their way back to God through direct personal spiritual experiences. 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.
Harold Klemp is the present spiritual leader, known as the Mahanta or the Living ECK Master.
