Invocations can be performed at any time to bring a closer bond between Keeper & spirit.  It is best to hold, wear, or have close, the vessel of the spirit you are performing the Invocation for.  You may opt to use Draws such as incense, or candles, to create a more conducive atmosphere to your efforts.

Welcome, hearken to my side
I call you with open arms
To ask you to be a companion
A loyal and steadfast friend am I
I invite you with white light
To ask your guidance and insight
Be unto me now and I will dedicate
My loyalty and admiration in return.
