J. Z. Knight, American New Age teacher and author
Judy Zebra "J. Z." Knight (born Judith Darlene Hampton; March 16, 1946) is an American spiritual teacher and author known for her purported channelling of a spiritual entity named Ramtha.

Knight has appeared on US TV shows, such as Larry King, MSNBC and The Merv Griffin Show, as well as in media such as Psychology Today. Her teachings have attracted figures from the entertainment and political world such as Linda Evans and Shirley MacLaine. Knight claims to bridge ancient wisdom and the power of consciousness together with the latest discoveries in science. Some of the ideas are similar to those of Shirley MacLaine, which were criticized for being "kindergarten metaphysics" by mathematician and skeptic Martin Gardner. Shirley Maclaine claimed in her book that she was the brother of Ramtha in their Atlantean past lives. Ramtha's teachings have been criticized by scientists and skeptics. The Southern Poverty Law Center has criticized Knight for "homophobic, anti-Catholic, anti-Semitic racist rants".Knight lives in a 12,800-square-foot (1,190 m2) French chateau-style home in Yelm, Washington, teaches courses and runs Ramtha's School of Enlightenment.Knight has been married three times and is the mother of two children from her first marriage, which ended in divorce.
