Your spiritual chills is that blissful energy that is most easily felt and recognized with your goosebumps (but not dependent on them).
It can be observed as a flowing hot or cold wave underneath your skin.
During their activations, try putting a positive thought form/emotion into your vibing energy and then sweep yourself up then down with it repeatedly.
Then, you can observe how you entering a room can cause lights to flicker, have a direct affect on the mood of people in it, or enhance someones mood with positive energy by laying your hands on their shoulder.
That is just the tip of the iceberg.
By practicing the same conscious energy sweeping of your whole body with it, you can attract back into your life people or events that matched the feeling you were implementing on your spiritual chills.
Different terms from all over the world for it are Euphoria, Tension, Ecstasy, Qi, Chi, Prana, Vayus, Aura, Tummo, Orgone, Kriyas, Mana, Life force, Pitī, Frisson, The Secret Fire, Voluntary Piloerection, Rapture, Ruah, Ether, Nephesch, Chills, ASMR, Nen, Spiritual Energy, The Force, Spiritual Chills and many more.
This comes from your energetic (spiritual) body.
Here’s a short Youtube Video that goes more indepth about how you can you use its incredible attraction force.
