You'll find these to be basic things that culminate in defense.
Basically Prayer repeated.
Things which you find improve your mental and physical strength and health. 
Writing affirmatively, strengthening in general.
discerning between things like the hoodoo in your mind they suggest something to you spoken perhaps, and something external a targeted. 
Using the Force of your will focused, at least in my experience not to attack somebody to drive something out.

Fire: i don't know how to sun gaze properly i just do it sometimes like picking at a meal. Exposure Sunlight in general. not a campfire but just warming yourself in general front and back before a fire- something to do with the cleaning the aura/energy.
Water: showering. Swimming.
Air: breathing and exposure to wind.
Earth: actually sitting on ground - dirt like in the garden, stabilizing. For a couple of minutes. contacting the feet and hands with that ground, perhaps simultaneously.

the lunar cycle, observe your condition towards and away from the full moon and no moon. dreams during then too.

Don't 'Sun gaze' like a motherfucker, i just look at it with eyes closed or half or so and very sparingly just to get a bit of stimulation. I don't know about fifth element, peering into the sky every now and then has a bit of an effect.
