A guide to the the relationship between the human iris and psychological characteristics. Written by renowned and established iridologist Peter Jackson-Main, this expertly conceived book provides a ground-breaking methodological model of how the iris might be used to understand the energetic, psychological and emotional attributes of a person. The analysis presented in The Mind’s Eye places energy as the central aspect of an individual’s reality. It argues that the physical body is an extension of such energy in the physical realm: a map of one’s intentions in manifesting as a physical being. Jackson-Main situates the irises as this map, which when studied will allow true depth understanding of the human body. The book begins with a brief examination of the epistemological foundations of accepted theory and practice in medicine and healing. It continues as a journey, exploring the development of iris analysis throughout the twentieth century, including information on the possibility of heritable personality traits seen in the iris. Jackson-Main then provides his own perspectives on iris analysis, in a manner which is accessible for both practitioners, and any lay-person looking to learn more about themselves. The book also contains a comprehensive guide to completing an ‘energetic’ iris chart, and suggested exercises of practice. Not only is The Mind’s Eye an indispensable guide for any health practitioners wishing to incorporate behavioural iridology to into their work, but it is also an invitation for all humans to embark on a deeply symbolic journey of self-discovery initiated through the marvels of the eye.
