Another shield I use
The Qabalistic Cross
To begin I would recomend that you bathe and clense your outer body. Once you have this down pat you can quite easily do it every morning if you want after your wake up wash. This is a personal choice but I like to do this nakied fresh from a bath or shower.
Stand quietly for a moment, breath deeply and rhythmically and still your thoughts. Let your mind go blank, casting off the worries and stresses of the day to come.
Imagine yourself slowly growing larger and larger with each breath you take in. You grow and keep growing like Alice in Wonderland. You become as big as the house you are in filling it all. Hold that size for a little while feel how it is to be so big. Slowly let yourself sink back down to your normal size with every breath you exhale, keep going getting smaller and smaller. Child size, baby size keep going till you can fit in a matchbox, keep going till you are the size of a thumb nail. Hold this size for a little while feel how it is to be so tiny, just a speck of dust in the grand skeem of things. Now slowly return to your regular size. Slowly now I want to you to make yourself lighter, lighter, keep getting lighter become the weight you were when you were tiny and keep going till you are as light as a feather or a speck of dust. Let yourself float upwards towards the ceiling passinf through the ceiling on up to the roof. Float on up into the sky look down on your own roof and at all the roofs in your neighborhood. Keep floating on up so the Earth is below you tiny and growing tinier as you continue to float higher and higher. Expand again growing bigger and bigger to fill space. You are bigger than the soloar system, the galaxy, all of creation. You stand in total darkness but you are not afraid, or cold or lownly.
Imagine that out of the darkness comes a brilliant beam of light that forms a brilliant swirling sphere of light just above your head. Don't force it just let it slowly form above you shining down upon you lighting up the darkness around you.
Vibrate the word "Atoh" or "Ateh" and gently bring your receptive hand up to touch your forehead. Abeam of light comes down from the sphere to your forehead as you touch it.
Picture this beam of light flowing down through your body down to your feet as you point to them and vibrate the word "Malkuth". The light forms another sphere here half above and half below ground level.
Now touch your right shoulder and visualize another sphere of light forming there as you vibrate the words "Ve Geburah".
Draw your hand across your chest and touch your left shoulder and form another sphere of light as you vibrate the words "Ve Gedulah".
You now have a cross of light extending from your head to your feet and from your right shoulder to your left.
Clasp your hands at the intersection of the cross. Vibrate the words "Le Olahm" as a fifth sphere of light forms around your hands. This sphere of light continues to expand untill it fills your entire aura. You are now in a sphere of light that totaly surrounds you.
At this stage you can do a number of things depending on what work you wish to do. I have used it to go effect as a shield but also as a means to blast negative things away from me. I will use this as an example here for now.
Picture the sphere of light at your hands becoming brighter and brighter, the good energy becoming stronger and stronger. Now picture the negative energy as a solid object before you. Give it shape and form. When you have both negative and posative fully formed with an exhaled breath open your hands and push the palms away from you sending a beam of intense light straight at the object of negativity. You may wish to say something also at this point, I have a flare for the dramatic and I always like the sound of the words "Be gone". Say them with as much force as you can muster and blast the negative form with that beam of light. Splinter it and blow it apart let the light fill every last bit of it transforming it from negative to possative. Bring your hands palms together once more when your work is done at the intersection of the cross once more.
Stand for a moment once more in your sphere of light and then vibrate the word "Amen"
