According to Ra, ambrosia is the food of 4th density

[Jade]

A small correction: Ra referred to ambrosia as a fifth density food. On the subject itself, there are 3D entities that feed on prana directly and do not need to eat food. Probably the feed at higher densities is similar.

This. In fourth density:

The fourth-density being desires to serve and the preparation of foodstuffs is extremely simple due to increased communion between entity and living foodstuff.

I think this implies eating raw vegetables and fruits harvested from living plants. This is the simplest version of converting light into food, and requires no untimely killing of any living entity.

In fifth density:

You would call this type of food nectar, or ambrosia, or a light broth of golden white hue.

I think Ra is talking about ingesting a formation of light as a sustenance. I don't think honey and bee pollen could be considered "a light broth of golden white hue". I do not believe farming animals for food is a part of any density after this one. Bees work very hard to create and store honey for their hive, humans are actually quite cruel to take it from them.

That which fourth density is not: it is not of words, unless chosen. It is not of heavy chemical vehicles for body complex activities. It is not of disharmony within self. It is not of disharmony within peoples. It is not within limits of possibility to cause disharmony in any way.
