Shielding

Shielding is a concept, that I learned in the early 90's.  I'm not sure of where the origins come from, and I'll try to research it and write about it, when I can find it.  Google Fu just returns a lot of skyrim wiki's.

Basically you imagine an energetic colored egg that surrounds you, with a silver line running into the ground(that silver line grabs energy to power the shield).  You can color that egg, for different things.  Blue is usually the one that people do as blue is protective color.  Others use a white light(cause white is the holey light of angels or some such).  You can do different shields and layer them.  You do the blue protective one, the white one, a mirrored one(literally a shield that looks like a mirror) make a rubbery one, and you can even chant the phrase, I'm made of rubber and you are made of glue, what you send to me, bounces off me and sticks to you.  Imagination here is key.

To do this, you use your visualization skills.  visualize and then if you can feel that energy encasing you and protecting you.  Let the silver cord trail from your feet into the earth.  Use your hands if you want, to bring up the energy.

The Christians have a similar shield.  It is called the Armor of God, you can try this technique as well.  quoting from wikipedia
The full quote as outlined in the King James Bible, is from Apostle Paul's letter to the Ephesians 6:10-18: (10) Finally, my brethren, be strong in the Lord, and in the power of his might. (11) Put on the whole armor of God, that ye may be able to stand against the wiles of the devil. (12) For we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places. (13) Wherefore take unto you the whole armor of God, that ye may be able to withstand in the evil day, and having done all, to stand. (14) Stand therefore, having your loins girt about with truth, and having on the breastplate of righteousness; (15) And your feet shod with the preparation of the gospel of peace; (16) Above all, taking the shield of faith, wherewith ye shall be able to quench all the fiery darts of the wicked. (17) And take the helmet of salvation, and the sword of the Spirit, which is the word of God: (18) Praying always with all prayer and supplication in the Spirit, and watching thereunto with all perseverance and supplication for all saints; ^[1]

You can do something similar with other holy phrases, that are more applicable to your religious choices.  You could also wear protective amulets(The eye of Horus, protection against evil eye, Hand of Fatima, Gods eye, Ankh, Pentacle etc) in addition to your shields.

Other things to think about.  You could visualize yourself in chainmail, plate mail, kevlar, etc.  Read up and think on what would be useful.

Heres a link to someone who also writes about shielding.  http://www.magickofthought.com/2010/03/effective-psychic-magickal-shielding/  This is more advanced stuff and I like what he has to say.
