Originated in India, yoga refers to traditional physical and mental disciplines that are designed to unite body, mind and soul for inner control and concentration.###
In western countries the generic term for the physical discipline is Hatha Yoga. It combines physical practices with breathing exercises and relaxing techniques focusing on the purification of body and mind to unleash the prana or vital energy.
Yoga has a positive effect on our physical as well as psychological health and may ease different kinds of illnesses, such as circulatory disorders, insomnia, anxiety, depression, headaches and back pain. However, as yoga touches the very core of ourselves, it can bring up certain emotions that may or may not be familiar.
A mental discipline of yoga and necessarily a religious practice is meditation.
