Keeping bowls of water may look like you have a ceiling leak but this practice has been used for decades as a way to trap and keep spirits and bad energy at bay. Typically you keep this bowls of water under your bed and regularly remove them. In this case since my bed is flush with the floor I keep it on my desk and near the entrance, You change this out. Some people get creative and add salt or Florida Water but this practice just requires regular tap. It is said spirits like standing water as can be seen on an altar with the glasses bubbling up when the spirits are said to be pleased and present. I have found that spirit even does that in these jar like vases. You toss them out in the toilet and flush. Let me know if you have any questions below.
