SURYANAMASKARS - HOW MANY ARE ENOUGH?

It has n number of benefits (you can Google those later) but it is not a number. It is not that a certain number of suryanamaskars a day will keep the doctor away, but it might keep you away in a few days if you treat it as numbers.
If practicing suryanamaskars daily is exhausting you, if you roll back into your bed after the practice or want to rest before beginning with your everyday chores, than you might be going all wrong with your inclination and intentions of doing it.
Rightly done, suryanamaskar will of course shake up those joints and muscles rusted by laziness and make them sore in the beginning but eventually it should be more energizing and restorative than tiring and exhausting. It is, after all called suryanamaskar for a reason, that it is a way of bowing down to Sun God and thanking for being the greatest source of energy. It is supposed to stimulate pingala nadi also called as surya nadi, that helps to tap sun's energy and remove energy blockages if any. But if you target to do so many suryanamaskars in so much time than you better call it burpees or something more fancy because it won't be beneficial as it should be if it is not done as a spiritual ritual.
So next time when you get down on your mat for suryanamaskar, switch off your phone, turn off your timer, silent your mind and just be in the flow, breath comfortably in all postures, stay as long as you wish in any posture letting it massage your muscles, align your mind in every pose and do as many as it feels good. Yoga is never about pushing yourself rather it's more about raising yourself. Numbers would increase on a healthier day and decrease on a not so healthy day; doesn't matter. What should matter is showing up each day and finding a new you after each practice.
