Phyllis Krystal was born in London England on May 11, 1914. She graduated from Bishop Otter College, Chichester and taught high school for three years before moving to the U.S. in 1937. She married Sidney Krystal, a prominent attorney, and they had two daughters and two grandchildren, a grandson and a granddaughter. She has been a widow since 1993.

In the late 1950s she studied the work of Edgar Cayce and was regressed into past lives. This led her to work with a friend and develop a method for contacting the inner source of wisdom which they called the Hi C for Higher Consciousness. Since that time, a visualization method has evolved by working with the Hi C which she first used on herself and then with many others. The techniques received from the Hi C have been used to help those who wish to release from attachment to or reliance on outer security or control, thus free them to seek guidance from their own Hi C. As word of these techniques spread, she received numerous requests to write about her visualization method. Her first book, Cutting the Ties That Bind, was published in 1982 shortly to be followed by Cutting More Ties That Bind and a Workbook to accompany the two Cutting the Ties books. Her other books are Sai Baba, The Ultimate Experience, an account of her experiences with the Indian master Sri Sathya Sai Baba; Taming our Monkey Mind; Reconnecting the Love Energy; Cutting the Ties of Karma; and her latest book, Let's Thank God.

All her books have been published by Samuel Weiser, now Redwheel/Weiser. They have also been translated into many languages, which has continued to spread her work even further and led to invitations to give seminars in many other countries, mainly in Europe, to teach the method and to give individual sessions. Now 94, she continues to write and lecture around the world and is currently living in Munich, Germany where her work is in great demand.
