I sometimes find myself a little stressed out. Especially while doing a healing spell. I find this incantation to help just before the healing ritual.
Lady Goddess give me rest
From the ills I know as stress
Allow me strength in everyway
To bare up well from day to day
Give me knowledge and the skill
To do no harm but as I will
Let not the spells come back on me
As I do will so mote it be
Blessed Be!
