Entity For Telepathy

Anyone know of an entity that can help with telepathy?Preferably one that’s easy to work with and a known sigil that works.

Paralda is a quite friendly spirit to teach you that, also a good one for the rest of the basics.

What Grimoire might Paralda be found in?

I never worked with him through grimoire tradition approach, but if memory serves me.well it was Paracelsus who first mentioned this being. I worked with him in a blind way, except for some stuff I had read about him in my early occult practices, but theres alot of info on him around the web.
