Whether you're new to esoteric spirituality or an experienced practitioner, this book provides a clear pathway to inner transformation through time-tested Rosicrucian methods. A must-read for anyone interested in practical spiritual development and the Western mystery tradition.

Book Review in the Paradigm Explorer of the Scientific and Medical Network
by David Lorimer
Rosicrucian Alchemy. Dr Peter Gruenewald.
"This book is subtitled ‘a spiritual Christian path to prepare the philosopher’s stone’ taking the reader on a deep dive into Christian esotericism
The main aim is to help bring readers into a free and loving connection with Christ through a process of alchemical transformation. The role of the Rosicrucian alchemist is to anchor the universe in being, renewing its spiritual existence and enabling Nature to breathe the presence of God again.
Spirit embraces and transmutes matter while transforming war into love to enable a rebirth in the Holy Spirit while recognising Nature’s universal dynamic of alternating coagulations and dissolutions and achieving rhythm, balance and harmony in a psychospiritual coincidence of opposites – the sacred marriage or hieros gamos.
This is a book to be studied that enables the reader to engage not only in a process of individual transformation but in the evolution of human consciousness as a whole."

Book Reviews for The Inner Sun on Amazon
Powerful solution
I believe that Dr. Peter Gruenewald has successfully accomplished his mission and vision of bridging the gap between science and spirituality in his latest book "The Inner Sun". This book teaches us a way to find our inner sun in a step by step guided Sun Meditation which he has developed, practiced, perfected and simplified for busy people like us to do over 40 days until it becomes a habit that we can integrate in our daily life. Doing this daily allows us to re-center ourselves and use the power of our inner sun to get us through the day with clarity, energy, strength and resilience. In this noisy and demanding world, it is easy to feel overwhelmed, exhausted, empty and lost. This is a simple and effective, practical and powerful solution. Thank you Peter!
Dr Cicket Chen, Paediatrician. Amazon Review from 07.04.2025
Great Practical Information
This is probably one of THE most useful books for a Heart Centered Meditation practice with absolutely zero fluff. It starts by discussing of what the Sun Meditation shown in the book is comprised. Mentions that although it emerged from the Rosicrucian path, it speaks to universal human experiences. Then it tells you how to use the book with a structured step-by-step guide. Then follows a complete quick guide for both morning and evening sessions. It also addresses some common questions and adjustments on the practice. This is all before Chapter 1 !!! The rest of the book gives much more fleshed out information on the actual how, what, and why. It introduces the four fundamental pillars of the practice helping you understand why it is so transformative. The book provides an online source to get a free Breath Pacer that may help with the breathing and mantra portion of the process. There are more suggestions for beginners, intermediate, and advanced stages of the work. I definitely recommend this book along with the author's second edition of Rosicrucian Alchemy: a Spiritual Christian Path to Prepare the Philosopher's Stone which gives so much more information on the Rosicrucian inspirations behind the mantric Sun breathing Medication.
