The word yoga means to unite, to join together or to integrate. Here there are several spheres of reference integration of the physical with the emotional nature learning to co-ordinate emotional and mental aims to integrate mind and body- and to join the individual soul to the Universal Life Source, or God.
The system known as Yoga is an integral part of the classical systems of Indian Philosophy, all of which stem from the ancient and profound Vedic teachings that are considered to have their origin in antiquity. The Vedas refer to all aspects of human life and the natural sciences, including those involved in the spiritual evolution and advancement of mankind. Readers may already be aware of the value of the therapeutic aspects of the teachings known as Ayurveda, the philosophic Vedanta (the last of the Vedas) and the poetic and mystical Upanishads. It is believed that all our great western philosophers over the centuries have dipped into and adopted these Indian wisdom teachings with the result that many similar ideas permeate their doctrines. Both the philosophic and the practical guidelines of old are a valued source of information that continues to inspire earnest scholars as well as all those who question life today.
