Crystal towers or Points also called generators, bring strong, grounding feng shui energy that is different from the energy of crystal clusters. The energy of a tower is directed upward and out. Wherever they are placed they emit a very focused and directional energy that affects the area around it. Ultimately, towers create a vortex of energy.
Palm stones are perfect to hold during meditation. Palm stones provide you with something to keep your hands busy or help you focus and stay grounded like a fidget device. Another way to enjoy palm stones is sleeping with them. If you have trouble falling asleep or staying asleep, palm stones are incredibly comforting to hold while you fall asleep. You can place it under your pillow if you don't want to hold it. I love that specific stones can aid us in sleep, lucid dreaming and dream recall.
Clusters are especially powerful with their output of energy. The points in a cluster vibrate together harmoniously to bring positive energy and transmute negativity in any space they are in. They can also help us feel more energized mentally and physically as well as aide us with decision making.
