The scripture says to go to your closet and pray in secret. In Judaism people often have a shawl they cover their head with when they pray. This is called a prayer closet. If I'm remembering correctly. The idea being not to try and put on a performance as to appear pious in front of others.
You mean going out onto the public square and shouting an ad hoc prayer into a loudspeaker doesn't count as going into my clause to pray?
