I’m thinking that I should add some context:
First, I begin as the tub is filling for my bath; stop praying to turn the water off; and then finish with the tub full.
Second, I am only partially prostrate on elbows with hands folded - or I would drown.
Third, I had a friend who told me that while she was in high school, she went to the chapel and prostrated in front of the. alter to pray for God’s help to get a good grade on her chemistry final. (We both had high school chemistry experiences that were traumatic at the time.). So I had always thought that I would like to try that prayer posture; and after I had knee replacement surgery in one knee - many years later - I thought about it again. However, I didn’t want my husband to find me stretched out on the floor so I decided to do it during my morning bath which I have found very rewarding - there are no distractions, the water is soothing, and I feel closer to God. Btw, I walk in the evenings while I pray the rosary - also very enjoyable.
