This Yoruba language greeting for a babalawo means "May the sacrifice be sanctioned, accepted and manifest!" and is like asking for a blessing that evrything will be well in your life with the help of the Orisha. This is the correct official Yoruba spelling. In Cuba people often say "Iboru Iboya Ibocheche" the roots of this variant lie within a Yoruba dialect (Ijebu, I think).
