Sun Salutation (Surya Namaskar) is a flow of 12 asanas performed in a specific order. It is meant to activate the entire energy system in the body in a balanced fashion. It is performed starting with the left side, followed by the identical flow on the right side. When both sides are complete, a full round of Sun Salutation has been accomplished.
In practicing Sun Salutation, we simply solute the Sun.The Sun being the center of the solar system symbolizing Ultimate Consciousness. Sun Salutation is known as a morning practice, as the air in the morning is super potent, filled with life energy; Prana. When done facing east (sunrise), breathing correctly, and for some, chanting the Sun Salutation Mantra simultaneously, one can experience an extraordinary effect, harmonizing & activating body, mind and soul.
