Why you have to do actions in a sequence and for certain numbers?
If "sajada" is physical prostration then why two times in one unit of ritual prayer and why 2,3 or 4 units in one ritual prayer?

If you want to practice ritual prayer as a Muslim culture thing, no problem do practice it and make yourself comfortable with it. But I could not find the ritual prayer as practiced by Muslim in Quran.
Anyways good logic this "God bless you" thing is also nonsense.
I don't think so because what I have learned from his posts he seems to have an honest heart. He just sent a sincere wish to you. For sure all blessings are from God.
