[Verriasana]

From what I understand about the raw astral elements (Eart, Air, Water and Fire) they attract the beings associated with them and they "frolick" in them. My guess is that any substance you create has an attractive power to watever beings are associated with it. In your case with the psi balls and the attributes you programmed into the psi, it attracted bug critters with similar attributes?

My advice would be to never let the energy your create si somewhere and stagnate or something could happen at your expense because the energy is associated to you since you created it.

I once put the fire element in a bottle of water for a specific reason and when I came back to the water a few days later having forgotten to "erase" itI got a stomache ache from drinking it.
