There's an old chant; "Untie a knot , tie a new knot, bind it and set it free."
It's all a matter of visualization, intent and Passion. Symbols or Icons , are particular to the magic, relative to the emotion behind what one feels the "need" to bind. Being familiar with color magic or energy association, is important if one cares to take it that far.
Healing for instance; The direction of the East is the portal of spirit. The left hand , if you spread your arms and legs apart one appears as the symbol of macrocosm. The left hand is the channel of spirit / universal power. Some people erect an altar in the East part of the room or grove, they work in so as to be at the threshold of that energies power source.
Purple, Lavender, Indigo. Perhaps for the aid of helping someone survive, recover, maintain remission, of cancer. In the darkness, in a quiet place, safe from interruption, that place where one feels embraced in their own thoughts , free of the outside world. Sit, with a single candle aflame. Perhaps the color of the yarn or other rope like material you are using for the spell.
First light the candle with a wooden match. Not a lighter. These are the old arts your intention is summoning. So maintaining an air of the old ways is in keeping with opening that channel, the door, to the mind and that place that is eternally present in the ether of re-call. If your altar or table, that the candle sits upon, needs a cloth or drape of some kind, choose what feels right to you, if anything of a cover at all does come to mind. This represents the root of the other world, the world of that one you seek to assist to gain strength in their personal challenge. It is your visual, mental and emotional focus point to "see" their need in their world. (Perhaps you can get a cloth that is that of their favorite color, or perhaps if they are fond of animals you might consider an animal print. Easily found at WalMart, or any sewing center. If you shop for such things do so with the one you intend to commit this working for, at the forefront of your vision. Have them in your minds eye from the moment you set off for that particular task at hand. Be it altar/table cloth, candle(s), incense, etc...) Ask the powers you intend to invoke for this work, to guide you to what is simply necessary and open to what answers arrive.)
When you light the candle focus on the one you seek to assist with finding their strength and inner guidance to the truth. Focus on the candle(s) on the altar/table. No other light to distract that visual cue, just the flame alive and independent , channeling the gate to insight.
When you feel ready, take the **string, yarn, etc... that you have selected for this sole purpose.
(Side note: **Consider cleansing the materials in this ritual before you begin. As they just came from the commercial market place and have had many hands (energies) infusing them since the creation of them began. Washing the altar/table cloth, in natural detergent without softener and letting it to line dry, for instance. Taking a ritual bath(shower) yourself before beginning, is always good to cleanse the body temple for the
soul purpose of giving oneself to the service of another.)
Cut a length of the yarn as long as from the tip of your middle finger (Think of the hands four fingers and thumb, as the five powers that imbue all creation. (earth,air,fire, water, spirit.)
The middle finger is the spirit point. And measure the string from the tip of the middle finger to the top of your shoulder. The distance should be roughly the same as that between that middle finger tip and the center of your forehead. (The third eye). (re; cleansing. Perhaps you can place the cut length into a earthenware bowl filled with spring water and sea salt, for three days , starting on the cusp of the new moon. (beginning of the waxing phase) (check your calendar or this
site, for times) right at the very last cycle of the dark mother. The dark moon appears ten and a half to fourteen days
after the full mother. (dark moon, or last of the waning phase just before she turns to the new light again). This time or any moon time you choose, can be utilized for all ritual preparation, including your bath/shower, if you so choose. Remember, there is power within you waiting to manifest your will. If it feels right, do it! Books are just other peoples diaries of that communication with the inner powers that are there to be summoned and speak. You are the channel of your will and intent, always.
Cleansing the yarn/string, during the last of the dark mothers cycle and at the cusp of the new daughter, allows a release of the material/commercial energies invested in creating the articles one works with. It then imbues, at the turn of the new moon, the materials with new light, new life, a fresh start, at your hands.
Untie a knot, tie a new knot bind it and set it free.
hold the string in the your left hand, the left is the channel to the spirit gate, (east , in that aforementioned human pentacle pose.

Run your right hand down the string, keeping the candle flame you had previously focused upon, in your minds eye as you close your eyes. See that flame in the darkness behind your lids. That beacon that keeps you connected to the subject of your work. (healing, in this example, and your friend/family member, etc..)
As you run your right hand down the string, see it as their body and your hands are that touch of healing and care, love and empathy, seeking to soothe the pain away. Visualize those special energies and emotions you wish to impart to the need of your subject (friend, family member in need of healing). See them as clearly as you can, accepting this gentle loving gift of your compassion and love to see them happy and healthy again.
Then when it feels right , open your eyes (or not. It's all your inner communication that guides you, through your emotional bond with this one you seek to assist in their journey. This is just an example generally). Begin to work your hands down the length of the yarn, tie a knot and imagine as you do, the twining of that thread encircling what ever it is that ails your subject. See "it" in your minds eye as you work, being encircled and contained , removed from your friends body so as to stop the suffering it causes there.
You may feel inspired to chant or say something as you do this. Words are power and as the currents of your visualization, your emotion for this work flow so to do the words that give your intention shape.
"I bind this cancer from doing harm" As you entwine the thread and make the knot. When the knot is finished see it taken from your subjects body, and lifted up into the fibers of the knot. Freeing the flesh of the torment there. Do this the entire length of the rope, get it all within the confines of those knots of purpose in healing the suffering, the pain , that cripples the body temple of your loved one. When you have finished tieing the knots the full length of the thread, tie the ends together so the entire piece is now bound into a circle. Once tied it no longer appears to have a beginning or an end. It is all contained there, away from the circle of energies that commune to manifest what you see as your loved one.
Bury the knotted piece in fresh soil outside at the North direction. North is the portal/gate of Earth power, and if possible, on your private property or somewhere where you
know no one will disturb it. (If this is not possible out of doors, get a ceramic/earthenware bowl and fill it with dirt from somewhere outside or if not available , untreated store bought potting soil. (can cleanse store bought soil by putting it in a different earthenware bowl than used for this ritual, in the east for three days and nights, to allow sun and moon power to remove the energy of the commercial market)
Let it rest in the soil, covered over completely, there for 3 days and nights. This saturates the fibers, that captured disturbance of erratic energies called "disease" in your friend, with the whole of power, so that the greater power overcomes the lesser and takes from it its power to be. In this case, "disease" "cancer", etc... On the fourth
day (preferably at high sun without overcast) , after another bath/shower, dig up the string and put a small iron cauldron or any fireproof bowl like container and sit this cauldron/container, back into the soil from whence you just removed it. Then untie the circle and visualize opening the loop and setting free the fibers that served to contain this trouble, healing them and thanking them for committing themselves to your bidding. See the fibers and each knot as you untie it, releasing like butterflies in a vivid burst of ascent into the purifying light of the sun. Lifting off and taking flight into the light, residue of disquiet, pain, suffering, burned away in the rays of infinite and perfect power.
After you've released every knot, seeing your friends body released of the grip of that disquiet held there in the body, hold the string with your left hand and run your right hand, wrapped around the string, down the full length , imagining your friends body temple pure, warm in the sun and perfectly free of all those points of pain and disharmony. Alive and pulsating with new life, new hope and health.
Feel all those emotions you have for your friend as you gently grasp the string in both hands. Speak to them, (the string) and send them a prayer that affirms their healing, rather than asks for it or beseeching for it. As your will has already affirmed the change that
is! See it as done, see what you want for your loved one. Healing, peace, health, as
present! Rather than a thing hoped for. See it as real and give it that part of yourself that makes it feel that way.
You know how someone you care for hurts and it's so easy to say; "I'd give anything if I could help...."? Give this. See it as manifest. Your friend
is as you
want and they want (it must be the will of the subject to
be healed. ) for the life you both hold dear.
After you have finished speaking your feelings and thanks to your friends spirit (the string), lay it down into the bowl and release them from the room. See the subject (friend) leaving the fibers of the thread and lifting through that eastern spirit gate, away and whole , happy and healed. So that when you look at the string again, it simply is string, with no emotional connect to your loved one.
Then take the wooden matches and burn the string, have a window open in the east (if possible in that direction or any window in the room will do. You don't want to contain the smoke in your sacred space) and release the work. Say something if you feel compelled, in thanks giving for the attention of the powers, to your will.
"I release you unto the primordial soul, thank you and be free".
When the string is completely consumed, bring the flames/smoke/ peace, by slowly pouring the water spirit over it, in a counter clockwise motion. This further releases the powers out of the area. Clockwise directions invoke or bring forth, counterclockwise releases power from a place.
You may feel like doing a meditation after this. What ever feels right, pay attention and choose.
Then when you are finished and the remnants of the thread in the cauldron are no longer smoldering, take the bowl/cauldron, outside and pour it onto the soil. Walk away from that spot, then walk to the grass in the nearby area and with your right hand pause over that spot and ask for the power to cleanse the cauldron of it's work. Then gently remove a handful of grass, (just tear it gently away) and place it in the cauldron. With your left hand swish it around as you would a towel, counter clockwise until the grass is saturated with the wet remnants in the bottom. Then take the handful of grass, as much as you can get out of the cauldron/bowl, and from a standing position give thanks and let it fall randomly from your hands, back to it's mother.
Then turn and walk away from the area and do not look back. It is over, your will is done.
