Focus energy to index finger?

[Unbound]

Yes, the electro-magnetic field is defined by the shape you assign to it, that is, the sphere. Energy balls are an incredibly common practice in many different systems of thought. We had about 20 people all pass along a single energy ball from person to person and add energy to it, I could actually physically see it by the time we had finished the first pass, and it was about a foot in diameter. The techniques I learned from a freemason is more about creating cycles or circulations of energy through the body. We also did some basic energetic "combat" training with the same guy.

You can also charge an energy ball with an emotion and send it towards someone. Wiccan mothers will use this to help their children get along by throwing "love balls" when they are not getting along.

The freemason used a donut shaped circulation of energy though, rather than a sphere.
