Infinite Tai Chi

'be still like a mountain and flow like a great river' Lao Tzu

The ancient Chinese art of Tai Chi is becoming increasingly popular in the West as individuals of all ages discover for themselves the physical, emotional and mental benefits of this holistic form of exercise.  Scientific research studies have found Tai Chi to be particularly effective for improving physical strength, balance, flexibility and cardiovascular fitness.  Significantly reduced levels of stress and anxiety have also been measured in those practising for as little as 8 weeks.

Ki – can be translated as the fundamental life force. 

Rei-Ki – consists of two syllables in the Japanese language.  ‘Rei’ can be used to describe the ‘universal energy’ or ‘the cosmic energy’.  ‘Ki’ can be translated to describe the life force flowing through all living things.

‘Reiki is an ancient and profoundly simple system of ‘laying on of hands’ healing derived from Tibetan Buddhism’1

'Yoga is mastery over the modifications of the mind' Yoga Sutra 1-2

Yoga comes from the Sanskrit root yuj, 'to yoke, harness'.  The word yoga has a wide range of applications and definitions in the Sanskrit language, including 'union, join, bind'.1

However, early on, yoga came to be applied to 'spiritual endeavour/discipline'.  This can be related to the control of the mind (manas) and senses (indriya).  This usage was recorded in the Taittriya-Upanishad, dating back to the second millennium BCE.2
