Magic Hands - Happy Hands, Hands of Power - is an example of a practical spell to empower us. The more advanced in magic you are, the more you can do with this; but it's a great piece of energy magic for kids as well.
For kids, you can have them draw around their hands first and write the positive energy they want for each finger on the paper. You can hang it up to encourage the kids to learn it and to use it.
There are lots of different ways to have fun with this simple spell.
It is particularly useful to raise energy at any time without other people noticing what you are doing, so use it for stress relief.
Of course, lovingly switching on your hands of power before handling any magical objects, doing healing, writing your love letters etc. seems like a really good idea as well :-)
Keep it light, keep it bright, keep playing!
