Telepathy, it has been argued, might be the mechanism involved in prayer and could provide scientific evidence for belief in prayer's efficacy.
However if one examines the scientific studies that have attempted to test the efficacy of prayer. one would have to accept the scientific results which indicate that telepathy is an illusion.
Some would argue that people who kneel and pray are irrational
others would submit that they are suffering from some sort of psychological disorder.
Surely the best way to communicate with someone you cannot see - but you believe is there - is to use a telephone!
surely this is seems to be a much more efficient and accurate way to communicate with someone at a distance than trying to read his mind through the invocation of prayer.
