I only invoked him once when i was starting i wasent developed but i was hearing his voice in my head saying very basic things i also remember a pressure in my heart chakra. That out of the way i want to say in greece there all christians but i dont really care the only reasson i dont have contact with him is because i dont know who is he really .

From my personal gnosis samael is the highest face of the 'devil' then we have lucifer , satan, lucifuge and some more each aspect has the same core but is completly independent with its own abilities and can coexist with the other i read a rite once about summoning lucifer and azazel while many claim they are the same. 

I would like a confirmation on this cuz i hate false knowledge. I understand if 2 beings have a connecion or an animal aspect however masks?
