The maths is fascinating. According to major studies, plants grow faster when
people pray for them. A group of ten volunteers who visualise sprouting seeds
can make a big difference. But add another ten volunteers, and the effect
doesn’t double ... it gets an incredible ten times stronger. Or, as Dr Hamilton
explains, "Group energy intensifies the intent by the square of the number
visualising.

So if a thousand people visualise then the power of intent is a
thousand squared, i.e. one million. Got that? It sounds complicated but the truth is simple - your prayers can make more difference than you know.
