Yoga means a discipline of the body and mind. It is for the common man, living a normal life, whatever his profession, class, caste, religion, age and nationality. There is nothing mysterious about Yoga. It is not a set of religious beliefs or practices. Its simple aim is to develop, through gradual stages to acquire self-knowledge trough the healthy functioning of the mind and emotions. This can be achieved by the Eight Fold Path: Yama, the rules of social behaviour; Niyama, the code of personal conduct; Asana, postures and exercises; Pranayamas, rhythmic breathing; Pratyahara, detachment; Dharana, concentration; Dhyana meditation; and Samadhi, illumination.
