Once you have chosen to take upon yourself the obligations of the practice of Witchcraft, then the effects, or the immanence, of this way of life will be bestowed on you from aligned intelligence, and so will the tests that accompany them.
Anyone who willingly opens themselves to powers beyond the veil of manifestation (as we understand it) opens themselves to the possibility of inner initiation.
Witches know that they are witches, but initiation is what seals that knowledge through the power of ritual and the intent inherent within the process itself, to deeper strata of recognition and response both within oneself and from the powers to which we are oathed.
Once initiation has occurred, there is no turning back you will quest all your life; it is not a thing to do thoughtlessly.
