Meditation is also a great tool for understanding yourself and the world around you, which becomes crucial to further magical exploration.
Examine the way you think, the way you feel, why you think, why you feel. Do not shy away or offer excuses. Simply allow realization to occur.
When you feel you have a working understanding of these aspects, turn your "gaze" outward. Understand within, then without.
This is also a great way to develop in general terms, by aiding in helping you find those areas where you'd like to grow.
From here, I do find that "basic" energy concepts are a good place to explore. You can do this within meditation as well. Sit or lay down in a manner that is comfortable to you but won't put you to sleep and allow yourself to relax. Focus on your breathing, and feel the flow of energy with every breath, in and out. Feel it coursing through you, around you. Allow it to create an image in your mind. Take note of how it feels on your skin, how it feels within you, how it feels against your palms and feet. How does it respond to your will? To your visualization? Examine every facet of it you care to. And then return to your calm, allowing the energy to disperse from where it came.
