These are certainly not the only meditative practices that are beneficial to witchcraft. Energy work is another excellent focus for meditative practice and if you’d like to learn more about this practice I would suggest taking The Witch’s Energy System course. This course teaches about the energetic body and many ways to harness this energetic system in the craft.
Once more, please be easy with yourself in your meditative exploration. These practices are meant to deepen your comfort with skills that are not naturally a part of our daily lives. They can have great benefits but they do not always come easily. Don’t overexert yourself or expect too much of yourself. Gentle, steady progress is far more beneficial than a hard push that leaves you exhausted and never wanting to meditate. Be kind to yourself, and enjoy deepening your practice through these creative meditations!
