The beneficial effect of practising yoga is well-cited and further evident in its phenomenal growth in recent years. The ancient philosophy behind yoga practice, however, is less well known in the west. In this spiritual book, the authors introduce the wisdom of yoga that leads to a way of life that is at least 5,000 years old in India. The word 'yoga' means union, and the teachings of yoga convey a union on all levels of being as the person is at one with itself, with the divine, and with nature. Presenting the key philosophical texts from the "Yoga Sutras", the "Bhagavad Gita", the "Vedas" and the "Upanishads" in an accessible, poetic manner, this book explores the recurrent themes common to all schools of yoga - explaining how they can be incorporated into our lives to deepen the yoga experience.
