Q: Why don't we see images or hear from non caucasian or european looking messengers, ascended masters or archangels?

A: I've seen images of them, and have read their messages. You must understand that the entities appear as they are needed in the given situation or timeline. This also has to do with ones perception. And what the individual is comfortable with.

The entity known to you as Martin Luther King Jr. is actually a "white" Pleiadian, spent most lifetimes as a "white man". But when a leader was needed, he chose an African american appearing physical vessel, and incarnated on Earth from Venus?!

Many great leaders, ascended masters and others have taken on different vessels at different times here on Earth and elsewhere.
