“I developed my teaching based on the philosophy of purification, regeneration and transformation after healing breast cancer through natural & mystic Self-Healing in the early seventies. I mentor students to become a living example of the laws of living in life and work — wisdom embodiment — and to share the truth as a teacher and guide for those seeking health and healing.” Farida Sharan

“What a truly inspired being, Farida is.  Most teachers exist somewhere between the id and the ego.  Farida occupies a space far beyond selfish existence and that made all the difference in my life.” Chris Whyrick, Naturopathy, Washington DC

“I am very much enjoying my time at your school. You have a vibrant lovely energy that surrounds you. Having you as a teacher is more than a learning experience, it’s also a spiritual journey.” Necia Betts, Utah

Farida’s first experience with Iridology in 1975 was when she was told her eyes had turned blue!!! She later learned the cleansing that had healed the cause of her breast cancer also released the yellow and brown pigments from her iris. During this healing, her vision improved to the extent that she no longer needed to wear glasses!

Teaching Testimonials

“Emotionally, I felt a great releasing of fear and an opening to the love that I need. The support that I feel from the school helps me to tap into my inner strength and connect to the strength and gifts that this world has to offer. I found Heidi’s teaching to be tremendously powerful and inspiring. I learned an amazing amount of practical information and thanks to the small class I have a chance to learn hands-on and am able to ask many questions. I now feel confident in my instincts and abilities with herbal medicine. I found such a broad and deep level of introspection during the three days of classes. The school encourages a profound level of healing and acceptance of our pain and challenges. Thank you.” Suzanne

Thank you, Heidi, for showing the way. I am grateful to have such an amazing teacher who has opened a new door for me to slowly walk into.” Lauren
