The final part of a successful magickal working is the ability to project the energies ... releasing them to go and do their work. This is quite easy for some, but difficult for others. This exercise will help you learn how to master this skill.
In this exercise, you are going to visualize yourself at the seashore, picking up a heavy rock; now inhale, and see yourself throwing the rock as far out into the waves as possible as you exhale. Watch it splash into the sea just above the horizon.
Now, look up again and imagine another horizon that is twice as far away! Pick up a rock twice as large as the first. Again, take a deep breath, and as you exhale, throw the rock with all your might. See it splash into the waves in the far horizon.
Repeat this exercise again a third time ... each time, increasing the size of the rock, and mentally throwing if harder and further than the time before.
Keep practicing this exercise until you can "feel" the release of power that goes out with the rock.
You will experience this same sensation during magickal work when you release (project) the energies you've raised to do their work.
This is a physical work out ... you should feel tired when it is over ...but exhilarated.
