This Chakra Yoga manual is the main book for the study of the chakras. Written and illustrated by David, it is a comprehensive explanation of the chakras from a western scientific perspective. It Contains many details from psychological influences to the connections of glands and organs in the physical body. With the practices in yoga this becomes an essential book for the understanding of mind/body medicine, as well as for going beyond the body.

This is a very good introduction to the whole science of yoga; it also makes the connection to the forms of yoga important for the development of each energy center and certain practices for each. Written from a scientific perspective, it defines the real energy world – from gravitation (Muladhara) to magnetism (Ajna) in ways easy to understand for normal educated people

The Healers manual takes us deeper into the body’s physiological functions and how the mindset and belief system can often interfere with how the immune system could be functioning 100%. The PDF version of the book contains many active links to scientific research and medical studies that help us build a better more positive attitude to support our own health.

Helping to understand how the immune functions work is a key to making it work better since it creates a stronger belief about our capability to repair our own body and maintain an automatic defence against any bacteria or virus which could potentially be harmful or even destructive.

Our misunderstanding of this system makes us vulnerable to negative suggestions, fears and worries about our health, and even creates health problems through the power of negative thinking – what is called the nocebo effect. This is the opposite of the placebo effect in which the power of believing in the healing power of a medicine makes it work for us.

Pranayama Yoga is the firepower of yoga, the wind that fuels the flames. The art of deep breathing takes a while to learn and of course much longer to practice. there are 46 different breathing techniques in this book, from the easy steps of each section of the breath to techniques that require weeks to perform. Some are for physiological benefits, some for emotional release, and some for mental clarity, but most of them are based on the ability to breathe with our full lung capacity to be effective.

Also, we need to be aware of the Prana aspect, which is considered more important than the air itself. The scientific explanation of prana is in the first part of the book, nothing mystical about it, any more than electricity is mystical.

Hatha is the classical asana practice. this manual describes 150 asanas, with photos and benefits of doing them. This book explains how to do the asanas, with pictures, and gives the benefits of each. If you can master these postures and movements you can also master your health. In the Chakra yoga system, the postures and the movements between them are combined with breathing methods which increase oxygen circulation to specific areas, targetting certain glands and organs. the flows, also available in video, are for all-inclusive health.

The asanas are the base for all of the modern “styles” of yoga, from Iyengar to Ashtanga to Bikrams to dozens of others available; these styles are merely the ways in which they are put together into flows. Some of the chakra flows are available on YouTube. Many are based on the Egyptian style of flowing the postures� into dances.

In the Science of Yoga there are many departments of learning, similar to the system in a university. These departments are not the styles of yoga that are now popular in the West. Each department is one of the forms of yoga that presents a unique perspective and system of knowledge to provide a deeper understanding of the science of yoga as a whole.

Within the sacred geometry of Yantra Yoga lies the secret wisdom about the angles of entanglement which manifest the reality we can perceive, shaped out of the total matrix of this ocean of invisible energy. Remember that there are zillions of these energy waves which in quantum physics they regard as "waves of possibilities" only forming into electrons or protons (possibly) with the influence of a conscious observer.

David first translated the Yoga Sutras in 1982, but has rewritten and updated the text in 2024, and even done some AI editing. This includes all four chapters, written from the perspective of experience and not intellectual interpretation and translation of the Sanskrit. Yoga is an experience that comes with persistent practice, which he has done over decades

This is the first part of David’s autobiography, covering the first three years of his adventure in expanding consciousness. It is called “Journey Out and In” because it began as a journey to explore the world as we see it on the outside, then transformed to an inner exploration of consciousness through Buddhism and Yoga as he travelled through the Orient to India. The Awakening transformation he experienced started him on a very different path from the first adult years in Civil Engineering.

The second part of the biography explains what happened when he returned to North America. One could possibly call it ‘culture shock’ as he realized he no longer fit into the civilization he had left behind in his search for purpose. The effect was such that he had to go south and live with the Mayan people of Guatemala, where he felt at home again.
