Why are women not permitted to practice the Saashthaanga Namaskaram but are permitted Angapradikshana? I refer to these two practices in particular as I was told that a woman's womb is holy and may not touch the ground.
The Sashatanga is where one lies down flat on the stomach with eight limbs touching the ground. The eight limbs are chest, head, hands, feet, knees, body, mind, and speech. This namaskaram is generally done by men.
Women do only the panchanga namaskaram and not the Sashtanga Namaskaram. The panchanga namaskaram is done when the woman kneels down with palms joined together or touching the feet of the revered one in front.
Suryanamaskaram, (sun salutation) is a series of yoga poses meant to give praise to the sun. This is a tradition, which allows eulogising Sun as God and getting health benefits due to exposure to Sun and doing various asanas.
One of the asanas in Suryanamaskaram is Ashtanga Namaskara. Even women can get benefit out of the Suryanamaskaram.
Why The Women Is Not Allowed to do the Sashtanga Namaskaram?
Though many say scriptures prohibited for women doing Sashtanga Namaskaram, in my view, it is during the pregnancy related issues, which were thought of by ancestors in prohibiting Sashtanga Namaskaram for women during that time, as they have to strain a lot in doing so, and sometimes causing injury to foetus.
In Angapradikshana devotees lie prostrate and roll around the temple. Generally this pradakshina will be done with wet clothes.
I don't think in this pradakshina also pregnancy women are allowed .
In Bihar, during Chhath puja time, women after getting their desires fulfilled, perform a prostration march as they head for the river banks. So prostration is not prohibited in all places and at all times.
