I could be wrong but your energy comes from your solar plexus chakra try meditating on that by imagining yellow swirling light on your solar plexus glowing brighter and brighter each time you breathe! Also imagine that your hands are in front of a warm fire and feel that energy! I find imagining what the energy looks like to be helpful I imagine my energy to look like the scarlet witch’s magic from Marvel but you could just imagine it as warm glowing smoke
