Learn correspondences. Like the symbolism of colors and the properties of herbs and gems. Also look into ceremonial magic and the basics of ritual. I would also look into how to construct an altar. It doesn't have to be path specific just add visual aids to help you focus while casting.
Knowing and practicle application are two very different things. What is the purpose of casting a circle and grounding and centering. What are you grounding and centering? Where does that energy come from? What elemental energies do you use? What is the purpose of your work and the goal that you do it for? I am trying to get a understanding of where you are at. Although it may seem very basic for some and a walk in a wonderland or game room for others but astral travel is advanced knowledge. At least as far as I am concerned.
Valid points. I am assuming you already know the applications for the things you've studied and are wanting to make sure you haven't left anything out? Just be open to suggestion and read. Read a lot. Read articles, books, and journals about magic and all practices of the occult. Also practice. Work with what you know. With enough practice something can very well become a part of you. Practice and study. We've given you tips now run with them and good luck!
