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 has been a widow since 1993.
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.
Her first book, Cutting the Ties that bind, was published in 1982, followed in 1990 by Cutting More Ties that Bind. A workbook to accompany these two books was also published. Her other books are Sai Baba, The Ultimate Experience, an account of her experiences with the Indian Master Sri Sathya Sai Baba; Taming the Monkey Mind; Re-Connecting the Love Energy; and Cutting the Ties of Karma. In addition two other titles have been published in India: Let’s Thank God and Ceiling on Desires. These books have been translated into many languages, thereby enabling the method to be shared with even more people worldwide.

Mrs. Krystal stresses that this is not a „quick fix“ method. Each person must be willing to practise the appropriate exercises, rather then expecting someone else to create a panacea to eliminate all their problems. Help is possible only if each person is willing to concentrate on bringing about the necessary changes and growth in him- or herself, instead of trying in vain to change someone else.
