According to my wife... there is a basics of yoga which is very similar to our namaaz. I forget what the technical word for it is. It is just 4 to 5 poses. Her suspicion is that the yoga of today could have been a namaaz thousands of years ago which morphed into today's yoga as Hinduism possibly started as a monotheistic religion and changed. Just a thought.
Hinduism was never a monotheistic religion and it dont have any kind of relation with Abrahamic Religion.
Namaz is good for life and soul .But it is not a Yoga posture .
Yoga is the finest contribution of the Indian culture to this world
