negative energies

One of the first things everyone learns in the world of meditation and/or what many call the world of the metaphysical is how to “use protection”… think of an aura-sized balloon around you filled with Light. However, the more I would think about this, the more I thought it didn’t feel right to me. Did I believe that I should retain my “personal space” ? Absolutely. But I would think, “Doesn’t putting a protective bubble around me make me more separate, when the quest is to remember our connection as One?”
