Yoga is the science of right living and, as such, is intended to be incorporated in daily life. It works on all aspects of the person: the physical, vital, mental, emotional, psychic and spiritual.
The word yoga means 'unity' or 'oneness' and is derived from the Sanskrit word yuj, which means 'to join'. This unity or joining is described in spiritual terms as the union of the individual consciousness with the universal consciousness. On a more practical level, yoga is a means of balancing and harmonizing the body, mind and emotions. This is done through the practice of asana, pranayama, mudra, bandha, shatkarma and meditation, and must be achieved before union can take place with the higher reality. The science of yoga begins to work on the outermost aspect of the personality, the physical body,... (it) aims at bringing the different bodily functions into perfect coordination so that they work for the good of the whole body.
Today, in the 21st century, a spiritual heritage is being reclaimed of which yoga is very much a part. While yoga's central theme remains the highest goal of the spiritual path, yogic practices give direct and tangible benefits to everyone regardless of their spiritual aims.
Physical and mental cleansing and strengthening is one of yoga's most important achievements. What makes it so powerful and effective is the fact that it works on the holistic principles of harmony and unification. According to medical scientists, yoga therapy is successful because of the balance created in the nervous and endocrine systems which directly influences all the other systems of the body.
For most people ... yoga (is) a means of maintaining health and well-being in an increasingly stressful society. Asanas do remove the physical discomfort accumulated during a day at the office sitting in a chair, hunched over a desk. Relaxation techniques help to maximise the effectiveness of ever-diminishing time off. In an age of mobile phones and twenty four hour shopping, yogic practices make great personal and even business sense.
