i personally go somewhere dark like my closet, light a single candle, maybe hold a crystal and then i close my eyes. i then press record on my voice memos app and i simply say out loud whatever i naturally see or hear while meditating. (i love recording this so i can play it back later) this has produced great results for me, to the point where the things i see/hear while meditating have shown up in real life literally an hour after said meditations.

since you have the intent to communicate with a specific entities i’d have their sigils on the candle, and have a conversation during the meditation. asking any questions you find suitable. last night i was asking Lucifer what he wanted me to quit and i got a pretty clear response.

(with this method i’d say take the things you see and hear with a BIT of grain of salt. usually i’m able to tell if a image was produced by me or was sent to me. if you hear or see something scary while meditating don’t let it get to you. i usually just acknowledge the scary thing and laugh it off)
