Peter’s Books:

Manifesting Your Best Future Self:
Building Adaptive Resilience

It’s easy to feel daunted by life circumstances such as the COVID-19 pandemic, and by the personal, professional, and financial challenges that are arising from it. Unhealthy levels of stress have become widespread, resulting in physical and emotional health problems such as impaired immunity, weight problems, migraines, insomnia, hypertension, anxiety, irritability, and low mood.
This book introduces a highly effective approach that helps you trade tension, fear, anxiety, anger, and sadness for love, appreciation, gratitude, and enthusiasm, even under pressure. 

The Quiet Heart:
Putting Stress In Its Place

This book describes a highly effective approach to stress management and personal development, and has been updated since the first printing. Using heart-based exercises that help manage and transform extreme emotions, it is possible to deal with many forms of stress, anxiety and depression, without resorting to drugs or psychotherapy. The benefits of these unique, easily practised exercises can be felt within days.

This updated printing contains new relaxation and self-motivation exercises, and a wider variety of case studies demonstrating real results. There is also a useful Question and Answer section which addresses common queries which have arisen since the publication of the first edition.
