Put your tools on the floor right beside your altar (if you have one. If you don't, you can use any table that is comfortable).

On the altar, have a glass or bowl full of water, a small plate with some salt on it, a candle, some incense (or a feather or a bell), a stone or some soil or a plant and a representation of the both the goddess and the god. [Note these shouldn't be the tools you will be charging. I know that it feels funny to be doing magic/charging with tools that aren't actually your tools but that's part of kitchen witchery and you have to start somewhere.]

Put the plant in the north part of the table (if you can situate the table so that the top part [the part farthest away from you] sits in the North that would be easier to visualize and worth with). Put the incense/feather/bell in the East. Put the candle in the South and put the glass of water and salt in the West. Put the goddess image somewhere in the center but closer to the west and put the god image somewhere in the center but closer to the East.

Sit comfortably in front of your table. Close your eyes. Take three deep breaths. On the third exhalation make an Ah singing sound. As you do so, imagine that the Ah comes out of you and out in a clockwise, circular direction around you and the table. The next exhalation should bring another Ah and have it go further around you to begin to form a sacred circle. Imagine that as you sing, you are forming a time and place away from everything but the work you are about to do. There will be no distractions because this is ritual space. It is protected and safe around, above, and below you and your altar.

Once you feel like you have a circle established, bring your focus back down to your breathing. You can now welcome the elements. If you want to do this quickly you can say something like:

"By the earth that is my body, by the water that is my blood, by the Air that is my Breath and by the Fire that is my Spirit I cast this sacred circle."

If you want to do each element individually, you can say something like the following. Imagine each of the things - get them firmly in your mind - as you say them so that their essence is present with you in the circle:
"I call upon and welcome Air in the East. I greet thought, intelligence, truth, the athame, the curling smoke of incense, an eagle playing on the wind the spring, the dawn and the skies overhead. Hail and welcome."
[Ring the bell or waft the feather or light the incense.]

Then, turn to the south and say:
"I call upon and welcome Fire in the South. I greet passion, sexuality, creativity, action, the candle flame, the bonfire, motion, the summer, and the noonday sun. Hail and welcome. [light the candle]

Turn to the west and say:
"I call upon and welcome Water in the West. I greet emotion, intuition, feeling, life's blood, the chalice, the quenching of thirst, the calming rains of autumn, twilight, the dolphin, the whale, the fish, the smallest stream and the deepest ocean. Hail and welcome." [drink a few sips of the water in the glass. Then take the salt and pour some into the water and mix it up. Imagine that the water is becoming a cleansing and purifying agent through the properties of the salt being mixed in. some people also visualize the birthing salt waters of the ocean.]

Turn to the north again and say:
"I call upon and welcome Earth in the North. I greet, stability, security, centeredness, the home, the hearth, practicality, the bear, the stag, the snake, midnight, the winter, the pentacle, the crystal, the tallest trees, and the richest soil. Hail and welcome." [touch whatever item you have to represent earth. If it is a rock, for example, hold it in your hands to feel its weight and solidity.]

Then, welcome the goddess and the god in their aspects at this time of year. The goddess lives in her aspect as the one who harvests the grain so others may live. She is both the blessed earth and the dark moon. The god is he who is harvested and sacrificed so that others may live. He is the acorn that falls from the tree, the gold autumn leaves, and the grain and fruit that are harvested now. Welcome this essence of life, death and rebirth, the never-ending cycle into your circle. If you do this on the equinox/dark moon this Thursday, then you will also need to honor the time of balance as it moves towards the closing of the year and you will need to honor the infinite possibility and ending of the dark moon.

Once that is done, bring your focus to your tools.

Choose the first tool that you will charge. If for example it is your athame, hold it in your hands and envision what it is you want an athame to do.
An athame can be used to create a circle (if that's how you will use it). It can be used to point the direction to truth. It can be used to cut herbs and other things utilized in magical work. It can be used for the Great Rite. It can be used to represent Air on the altar table.
If you plan on using it for all of these things, then think them and visualize all of these.

Then, say something like:
"I pronounce that this athame is my ritual object. It will [list the things that you want it to do and imagine it doing those things]. I am bound to it as it is bound to me." Then, take the athame and move it in a circle three times around whatever represents Air on your altar.
Say, "three times 'round Air," and imagine the properties of Air of truth, honesty, intelligence, etc. lending their attributes to this tool. Then, move it over the candle and wave it over the candle three times in a clockwise circle. Say, "Three times 'round Fire," and envision the properties of Fire of passion, creativity, etc. infusing your Athame. Then, move it over the salt water and wave it over the salt water three times in a circle. Imagine the attributes of Water (feeling, perception, intuition) lending themselves to your athame. Then, you can either dip the athame into the water purify it or you can sprinkle a few drops on it. Next, move it over the crystal (or whatever represents Earth) and do the same thing. [Note: pay special attention to the element that governs the tool you are charging. So for the athame you would pay special attention to the east and for your chalice you would pay special attention to the West.]

Once that is done, put the athame in the center of the circle and say something like: "By the grace of the goddess and the god and by my will, I charge this athame as my ritual object. I shall care for it and shall use it with ease and grace for the good of all and with harm toward none. So I have spoken so it shall be done."

Then, do this for each of your other objects.

Once you have completed charging each of the objects, you can thank the goddess and the god for their presence in your circle, then thank the elements/directions in the reverse order in which you welcomed them. After that is done, sit for a few minutes in silence and ground your energy back into the earth. You can imagine roots that gently sustain/connect you to the earth or whatever imagery works for you. Once you have done that, you can open the circle in your imagination. Say something like: "May this circle be open but unbroken. May the peace of the goddess be ever in my heart. Merry meet and merry part and merry meet again.
