Love is the highest vibration, so when we stand in the love frequency, we instantly transmute all lower frequencies, thanks to the Law of perpetual transmutation which states the higher vibration/frequency always cancels the lower one! Very handy indeed, so we really have no need for protection!!
Some days however, we might be a bit off, so shielding can really come in handy if we are not hanging in that love vibration! I firmly believe that "needing protection" from lower vibrations is a 3D disempowerment program that I no longer choose to participate. I am the frequency holder, it's my job to transmute them! So I choose love! Shielding however, is just logical and empowering because you are choosing to shield, u recognize and choose to add a little loving insulation to yourself at that moment.
