Ok, so this may be a tad weird, but I was inspired to have a few words to accompany each visualization.
:Shield / Orb
- Whitest light surrounding me
Absorb and purify this energy
As I will,so mote it be

: Draining
- Liquid black negativity
Drain thee at once from me
Out my feet, into the ground
Mother Earth, to purify and bound
As I will, so mote it be

:Breathing
- Inhaling, drawing in white energy
Exhaling stress and negativity
Blackest smoke, now leaving me
As I will so mote it be
