Many people begin yoga for the physical benefits it is known to have, joining a studio in the hope of shedding extra kilograms, toning the muscles or simply as an alternative to repetitive gym routines. Although these desires are valid and are almost always fulfilled during the course of regular yoga classes, most students will be surprised to find a strong spiritual element at the core of their practice. Regardless of what religious beliefs students may have, they will discover that yoga taps into the commonality of the human spirit. It becomes a deeply personal endeavour - many people regard it as self-therapy as well as exercise. The mental benefits are profound. Concentration and focus is enhanced, incessant thought-waves are harnessed and complete relaxation is achieved. The mind is in state of peace wherein body and soul reach equilibrium.
