The Howlite is the calming stone. It calms stormy emotions and an overactive mind. It helps alleviate rage as it absorbs your uncontrolled anger and that of others towards you. This stone also helps prepare you for wisdom and insights from the spiritual dimensions. It also helps articulate and achieve spiritual and material ambitions.
In essence, if you are looking for a calming stone, the Howlite is the stone for you.
How to cleanse
The Howlite, like most crystals, should be cleansed periodically.
My best recommendation for cleansing your crystals is to do so with smoke. This could be from sage, Palo Santo wood or incense sticks. Allow the smoke to engulf your crystal and visualize its energy being renewed. After cleansing it, set your intention for your crystal by holding it in your hands and speaking your affirmation into it, specifically related to calming your mind and accessing past-life memories.
Sleeping with a Howlite crystal under your pillow is an excellent solution for insomnia. In addition, looking at this stone for an extended period of time can take you to other times and dimensions. Placing it on your third eye also opens you to past-life memories.
