The universe runs on energy. Everything in it is affected by energy. From gravity and electromagnetic fields to the heat that radiates from your body to the subtle energies of faith and spirit.

There are ways to learn to affect the energies around us, on a subtle mystical level. This allows us to have some additional impact on the world around us. But consider this example.

Many people think gravity is a very strong force. However, in reality, gravity is an extremely weak force compared to (for example) magnetism. The entire earth is generating the gravity holding a paperclip down. But it only takes as much magnetism as can be found in the size of a dime to lift the paperclip against gravity.

Mystic forces are even more subtle. They nudge and tweak and tip the balance against the more obvious forces that physics already recognizes. Compared to these other physical forces, the mystic forces are almost too faint to for most people to recognize. And because we don't yet have machines to measure them, most people don't believe they exist.

But ask any person who got what they prayed for, or any person whose thoughts manifested into reality, and they'll tell you that these forces are just as real, if more subtle.

How do you block hostile energy forces? The same way you would with any other type of energy. Just as you would use insulating materials to block electricity (which is why your power cords are wrapped in plastic), you can use insulating materials (silk works well) to block subtle energies. Just as you can use electromagnetic fields to contain radiation, you can use faith and prayer to block harmful mystical energies.
