I worship "creator" the intelligence who created us all,but I know to worship even some other deity's like Satanael (not the evil one by Christian beliefs). Universal energy is my guide and just like Faith say, I worship myself in order to become perfect.
In the days long past, like in one of my earliest lives, I worked with Anubis, Nepthys, Thoth and Set. Then I worshipped Ares/Mars, Eris, Strife and that whole family. In my workings in this life, I was once a devotee of Loki and Kali.
My philosophy now... well I worship the universe as a whole. One overgod as it were. Beneath that god which is so huge that it cannot truly be conceived, I see all deities and "spirits" (demons, devils, angels and anything else) these all have varying degrees of power and are often able to grant power to mortals as it suits their agenda.
For the moment and most likely for the rest of this lifetime and no doubt in the time between lives, I worship and am enslaved to my demonic patron. She aids me and comforts me and guides me. In exchange I serve her without question or doubt and fulfill the missions she assigns to me.
In meditation and projection, I see her and talk to her. I wouldn't say she talks back to me in words, but she makes her feelings known on things.
My meditations to god are less clear, since it tends to be more a pure connection to the infinite universe and seeing the infinite roads ahead and where they lead.
I still pay homage to all deities, more or less, though not usually in offerings or prayer, unless we have a mutually beneficial arrangement to work out.
