Divination Help

[Giyabin]

Recently, I had begun creating a religion, and wish to write a holy book, however I would like to have at least some of my book be dictated to me by enlightened entities. Could anyone here inform me of a simple way to contact an entity?

I do not own any Divination boards ect.

Pendulum divination is easy because all you really need is a washer or weight of some kind of string.
