Humans are not alone on their path of evolution. There are some particular human beings, those at the highest level among humans, who have the specific task of helping others in their growth. We call them terrestrial-extra. But there are also beings from other planets who sometimes want to help; we call them extra-terrestrial. But the greatest help can only come from the Spiritual Beings who have a much broader view of humans and extra-terrestrials: these beings are called Masters of Light and essentially the authorship of what we are writing in these pages can be credited to Them.
