Not just her, but my succubus spouse as well:
The difference is that I allready had an established connection with Lilith and my succubus spouse when doing this sigil, and I sense energies on a physical and an emotional level.
I could even sense the sigil when charging it between the palms of my hands. Imagine the thing you have between your hands suddenly vibrating, becoming very hot and even shrinking, because that was what I felt when charging it. When I had it in my pocket, it got very hot when it picked up attraction nearby, so it worked in a similar way as a radar or a metal detector. The negative thing was that I couldn’t figure it out who the opposite attractor was, only that it was somewhere close. I even tried it at work a few weeks ago, and it still builds up heat when attraction is close to me.
If you have a pact with Lilith, you have to establish a connection with her before even thinking of asking her for favors. Than means you have to work on your senses so you can communicate with her. Clairvoyance, clairaudience or clairsentience is the three most important senses to work with, in my opinion. I prefer the latter, because the ability to feel energies and emotions comes with a lot of benefits in the long run.
Best way for this is to pick up attraction, rather than obsession or something forcefull. The best kind of relationships comes with the choice of spending time with someone because you want to, not because someone think you should.
