Casting Directions for ‘How to Establish your Altar’
Some peoples are practicing magick for quite a lot time and claim to be doing magick with no altar or some other ingredients and can do magick all by their own style may could be stated as chaos magick itself, where on the other hand some individuals cannot perform magick without the altar or any other ingredients, especially in real they make a positive energy field all due to the power of faith of the spell caster results in the success of the spell being casted, some are even people who perform spell Casting from the Astral plane just like me, Said to be in an Astral plane temple build on the individual’s own thoughts and will, where the altar and other stuffs are easily gained, of course by power of mind.
These are the Styles favored by peoples and their might can be some others fashions.
My opinion is that select any style to cast a Spell, and should you want to use the altar pick any altar setting fashion or stuffs you discovered and which you found loved and easy too.
So when you get your altar and all the ingredients some basic things are they need to be cleansed and even blessed, these two are can be done easily, their are numerous techniques for the same like use of table salt, some herbs and many…
My opinion is the use any techniques you would like, for cleaning also, well you can use a psi ball to, or some use their mouth blow for it.
Mouth blow is easy you just have to imagine that the air blown from the mouth is of golden colour and is cleansing away all the black colored shades(negative energies), and thus making the object or any being glow like gold too.
You can even earn a shield, a magic orb around the object or a being, just imagine that a white color energy is coming from your hands(hands pointed towards the object or being) creating a shield.
And about blessings witches call upon their altars to be blessed by deities, Yes you can,
You can cast some spells or prayers.
May this helped you ^_^
