Just because you’re keeping the seal open, it does not mean Asmodeus is staying around. He’s got better things to do than wait for you to give him a task. However, open seals are conduits for energy and leaving it open to flow undirected into your life can have unpleasant effects. It can cause chaos in your life as well as attract parasites who want to feed on the energies and on you. It can also leave you paranoid and haunted. This is why seals are closed as soon as a result is manifested.
for sure tbh, in my case, literally every single time I sleep with a sigil under my pillow from any entity i seem to have parasites attack me during the night with such terrifying nightmares. It’s not normal nightmares, I know the difference.
I just hope that after a level, parasites stop being capable of approaching the Mage, if there is no such level its a problem, i dislike having to keep taking this subject seriously for eternity, i just hope at some level one becomes above that subject by definition..
It’s not bad - this is exactly what vessels aka idols are for. You have a statuette or something that represents the entity and invite it to inhabit it.
These are often kept on altars, but I have several and they are on shelves and my mantelpiece.
What do you mean by summoning? Have you done extensive ritual work to fully invoke or evoke or was it more in the line of sigil gazing and enn chanting in meditation?
Asmodeus is mainly a popular choice as embodiment of lust, but do keep in mind he is also an embodiment of wrath. By keeping a line open to his energy you do invite both in your life.
You can “pray” to Asmodeus on any day of the week, not just his assigned day. Most practitioners don’t subscribe to specific correspondences. They can be helpful but they’re not mandatory to follow.
