Surya Namaskar or Sun Salutation is a sequence of 12 powerful yoga poses. Besides being a great cardiovascular workout, Surya Namaskar is also known to have an immensely positive impact on the body and mind.
Your body is like the wick of a candle, and the mind is like the glow all around it. Prana is the vital energy needed by our physical and subtle layers, without which the body would perish. It is the prana or life force in us that nourishes the mind and keeps the body alive.
Nadis are subtle energy channels in the human body that can get blocked due to various reasons. The Nadi Shodhan pranayama is a breathing technique that helps clear these blocked energy channels, thus calming the mind. This technique is also known as Anulom Vilom pranayama.
