I'll just stick with John Climacus, Avila or de Sales, thank you.  Stupid sayings like, “Think of the sign of the cross; it’s a mudra. It’s a hand motion that opens us up to grace,” are the reasons people questions practices like this and whether those who promote these actually know what Catholicism  teaches.  Prior to suggesting something is in line with Catholic thought, a better understanding of Catholic thought may be in order.
