Philosophical considerations. What a meditation about the name of some higher being. Angel, a demon, a pagan god or goddess. And ask him/her what he / she thinking about it. But take it a time. So, patience is needed.
Like for example Hindu bhakti-yogis. See Ramakrishna and his vision mother Kali.
Or like adepts ancient mysteries. See Iamblichus: Theurgia, or the Egyptian Mysteries..... etc.
