Rosemary is renowned in herbal lore as a concentration aid. Whilst working evaporate the oil to keep yourself focussed. Dried leaves can also be steeprd in boiling water and drink as tea. My personal favorite is to keep a rosemary plant close to where you work. A gentle rub of the leaves releases a magical, refreshing fragrance ideal to help you focus.
Keep a quartz cristal in the water container you use the most. The longer the crystal is in soak, the stronger the purifying properties of the water will be. As you drink the cristal water, feel it cleansing your subtle and physical bodies, brightening and energising your chakras.
