There are quite a few different consecration rituals but this is the one that we usually recommend. There is no one right way, nor is there a wrong way, so feel free to adapt the ritual if you wish.
You will need a white candle for the consecration flame, water, pentacle and incense.
Cast your circle.
To consecrate the tool, the elementals may be used.
Pick up the staff, saying: "I have chosen this staff to assist me in my work."
Visualize the staff being cleared of any negativity.
Continue till the staff feels clear to you.
Now visualize positive energy flowing from you, down you arm and into the staff.
Visualize a strong white light flowing through your body to the tool. Feel it absorb the positive energies.
Point the staff towards the North, saying: "May the powers of the Earth cleanse and fill the staff I have chosen."Touch it to the pentacle, saying: " In the names of the Goddess and God (use any names you wish), I bless and make sacred this staff, tool of my craft. I charge this staff by the element of Earth."
Point the staff to the East, saying: "May the powers of the Air cleanse and fill the staff I have chosen." Pass the staff through the smoke of the incense, saying: "In the names of the Goddess and God (use any names you wish), I bless and make sacred this staff, tool of my craft. I charge this staff by the element Air."
Point the staff to the South, saying: "May the powers of Fire cleanse and fill the staff I have chosen." Pass the staff quickly (the staff itself is obviously flammable) over the candle flame saying: "In the names of the Goddess and God (using any names you wish), I bless and make sacred this staff, tool of my craft. I charge this staff by the element Fire."
Point the staff to the West, saying: "May the powers of water cleanse and fill the staff I have chosen." Sprinkle the staff with a few drops of water, saying: "In the names of the Goddess and God (using any names), I bless and make sacred this staff, tool of my craft. I charge this staff by the element Water."
Then say: "This tool is now ready, being consecrated and charged to assist me in my work. So mote it be."
Perform other workings if you wish, then close the circle
