Forming Circles of Light - by Dorothy M Rowatt. Many of us who have an interest in spiritual matters and complementary therapies, will have no doubt about just how important prayer is in our lives. However, a few years ago I was interested to discover the outcome of a scientific documentary on the power of prayer. When we come together in prayer, a circle of Light surrounding the one we are praying for is formed. Those who have a sixth sense can often see or feel it.

The ultimate goals of this blog are to inform, to share, and to have a positive impact on teachers by communicating professionally and blogging appropriate materials pertaining to curriculum and instruction which will improve student achievement.
