True, but the Orans position of prayer is traditional for the person leading prayer or worship or for self prayer.
The position of the hands is meant to help focus your spirit. Hands clasped and pointed towards the Altar and/or God helps focus all your attention on God. It’s also fascinating that this traditional prayer position is used by nearly every religion world wide. Christians, Muslims, Hindus, Buddhists, etc.
The Orans position focuses your spirit on collecting the silent and/or verbal prayers of others and funneling them through you to God.
For example, if a mother or father were leading a family prayer, he or she might use the Orans position to collect the prayers of the household and funnel them up to God.
The Orans position is also a traditional hand position while sitting, either with arms outstretched or down to the side with palms up.
The crossed hands on chest position is not one I’m completely familiar with. However, I THINK it’s purpose is to engage in competitive prayer by focusing on your heart beat. I don’t think it’s used too much anymore because such practices can be confused with Eastern and New Age beliefs.
NOTE: I agree with Archbishop Sample, that it’s not something worth getting upset over. However, like the good Archbishop, I too find it curious that some people who INSIST on using the Orans position refuse to bow their heads at the Name of Jesus, the Holy Trinity and the Blessed Mother. And they refuse to do a profound bow during the creed and sometimes do not tap their chests with their fist during the Confiteor.
