Trump Vs. Clinton
You can replace shielding with crystals... So you do not burn yourself out...
I appreciate what seems to be your advise (hopefully) intended to help. But you are off there, I am pretty sure! As I said - I ask for protections - as much and strong as necessary, possible, available and sensible! And I fully trust that I am provided with such ( I stopped trying to regulate and visualize them myself years ago, as I kept on getting into fears about: 'Am I doing too much, am I not doing enough, are my protections infringing upon other being's free will, etc....". So I leave those decisions up to my helpers and protectors!). If you indeed see very strong protections around me (and they are indeed there), it would be that I need them - living in a 10Million Metropolis after all. So even if they fed off my energy only (which I doubt very much), they would likely be of more benefit to my wellbeing, than less. I also have a quite a few crystals in the house too. I really appreciate their help, but I reckon I'd have to live in say a crystal pyramid to shield off/ divert more energy...(plus have visualized a few of those on the house in the past, which did not really change much besides being pretty and comforting)
Also I ask that all my protections are semi-permeable - allowing good energy flow unhindered, only impeding confused energies. as applicable and sensible (the rest being sent into Light, or grounded off without having to go through my bodies....)
On top of all that - what works for some might not work for others, as they might have different affinities, might be at different stages of their development, and or be dealing with different energies (in their battles), or different amounts...
Love and Light!
