The Universe is composed of energy. Everything around you -everything you see and many things you don’t- are composed of energy.
You, too, are composed of energy. Your body, which seems so solid, is composed of endless numbers of microscopic particles held together at the sub-atomic level by energy.
Science has taught us this. But the Vedic sages of India have taught this too – for many thousands of years. In Europe the Druids, and after them the Witches, recognized this fact as well.
