Phyllis Krystal was born in London, England in 1914. She graduated from Bishop Otter College in Chichester and taught at the high school level for three years before moving to the United States. There, she married Sidney Krystal, a prominent Los Angeles attorney. They had two daughters, one of whom gave them a granddaughter and a grandson. Mrs. Krystal was a widow from 1993 until her death in 2016. In 2004, at the age of 91, she moved to Munich,Germany and at the age of 95 moved again to Zurich in Switzerland.
In the late 1950s, Mrs. Krystal and a close friend embarked on an experiment to make regular contact with an inner source of wisdom, which they eventually called the Hi C for Higher Consciousness. Since then, by consulting the Hi C, a visualization method involving the use of symbols has evolved. These techniques can be used to help those who wish to release from attachment to - or reliance on - any outer security or control, thereby freeing the individual to seek help and guidance from the Hi C rather then from these outer sources.
For more than 25 years, Mrs. Krystal has given seminars in numerous countries - primarily in Europe - to share the method. In addition she has offered individual sessions to outline a program for achieving more personal freedom.
As word of this method spread, Mrs. Krystal received numerous requests to put it down in writing so the techniques could continue to help others, if and when she is no longer available.
