How can I summon Enki?
[Moved as this was off topic for the OP]
We have at least 4 tutorials for evoking entities, I’d suggest reading through all and picking the one that calls to you best
S. Rob has two books on Enki that teaches you how to contact Him. I’ve read the one titled Enki Sumerian God of Magick. It’s a short, practical read with over 15 rituals to get you working with Him. It’s $3 on Amazon Kindle. Definitely worth a read.
