To cast, simply recite the spell with the full weight of your energy & intention behind the effort.  You can recite out loud, or through telepathy (your mind).

If you feel you need candles or other draws like incense or stones please use them if they make you feel in the appropriate state of mind.

Or if you'd like to bind the energies of the spell to a stone for boosting purposes use these instructions with a candle:
Pass the rock over the flame three times after the spell is recited.
Keep the rock near you to have the spell surround you.
You can use the spell as much as you like!

Astral Door

I open this portal for the white spirits only

Bar and block the black energy

I open this portal to travel to the astral planes

That I can revel in the company of great beings

Show me the gifts of the astral domain

That I can be in greater knowing

My knowledge and intellect expand

My spirit grows and becomes stronger!
