We can't help constantly observing that there are so many parallels between Islam and the system of Yoga. One of them is giving preference to the right side.
Often during a yoga class, the instructor tells you to roll to your right-hand side after relaxation or savasana. Most asanas are also performed from the right to the left and not the other way around.
In parallel, were instructed by our beloved prophet muhammad pbuh that the right hand/ side always, takes a higher status, preference or position in terms of positivity then the left.
Have you ever wondered why?
Symbolic: First of all, rolling to the right or the right side has a symbolic reason. In Indian culture as well as in Islam it is considered more auspicious to enter a holy place with the right foot and in many parts of the world we extend our right hand in greeting.
Energetic: According to yoga teachings you also have a subtle or energy body, besides the physical body. This energy body comprises of chakras and nadis, making up many thousands of energy lines or channels. The main energy line runs along the length of your spine and is called shusumna. Spiralling either side of shusumna are pingala and ida, which end at the tip of the right and left nostrils respectively. Pingala on the right side represents the masculine forces of heat, activity and alertness or the sympathetic nervous system. Ida on the left is more feminine, cooling, passive and restful, referring to the parasympathetic nervous system. Rolling to the right side after savasana can help us to wake up by stimulating pingala nadi. In this way, we prepare ourselves to become more active again after a deep relaxation state.
Physiological: There is also a medical explanation to roll to the right side rather than the left. Since the heart is on the left, rolling to the right brings the heart on top and therefore puts less pressure on the heart and helps allow the blood pressure reach homeostasis.
In Yoga laying down on the right brings the heart on top, regulates the pulse, prevents compression in the heart and frees up the nadi (channel) associated with the left nostril.
