To Call upon Knowledge and wisdom place your Pentacle or Pentagram on your altar along with some sage Light a White candle anointed with peppermint oil then call upon the lord and lady by saying:-
"Lord and Lady I call upon thee,
and they high powers to awaken within me, 
the knowledge and wisdom from the corners of the earth,
far and wide of ancient Birth,
give me insight and knowledge true,
in all I say and all I do.
To be ruled by spirit as it should be,
as I will it so mote it be.
and it harm none so be it.
Blessed Be"
