I'm a beginner to practicing Psionics, and I've successully shielded, formed psi balls, cleared my mind when needed, grounded, centered, etc. So, I'm trying to practice ESP skills. Specifically empathy and telepathy, but from everything I've read, psi sigs are needed to do so. So, what are them exactly? I have a general idea, but when it comes to me determining what the sig of a certain person is, I go brain dead? Might I just be overthinking this? Help! ???
