There are a bunch of methods and everyone has their own. Personally, What I do is add crystals to the water and bless it under the moon light or sunlight depending on the deity you wish it to be blessed by. But really I do a few things, here is the way I do my own blessed water.
Quartz Crystal or Celestite Crystal or whatever crystal you like
- One moonstone or Agni Gold Danburite depending on whether or not I am invoking the blessing of a solar or lunar deity.
- You can look up a chant/prayer/blessing of this particular deity, for example: prayer to Ra the sun God or to Selene the Lunar Goddess or create your own.
- If you want you can also add some herbs to the water (optional) I use Frankincense because it cleanses and protects the soul and well it was and still is used by my ancestors and many other peoples.
- So I add all the ingredients to a large bowl or vase and sit them out under the sun or under the moon, while I am doing so I call on the deity of my choice (you can call on several if you like) and ask for their permission to bless this water, this natural element of life so that I may be protected and cleansed as well as my home and children etc, then I do my chant/prayer/blessing etc.
