Esoteric, is only a label.
These types of writing have many labels.
Such as Theosophy, Alchemy, Hermeticism, Religious etc.
But all of the types have the same goal.
The attempt to put into words, the expanse beneath, through, above and beyond human being.

This is what the metaphors attempt to describe.
Whether the topic is plants, chemistry, astronomy, architecture, biology or many other such areas of focus.
The specifics discussed are of these aspects of human being.

These aspects being the foundation that supports the commonly understood and discussed attributes.
That use plain, non-metaphor, everyday language.
This common understanding is the tip of the iceberg.

A recommendation, that would have been helpful long ago:
When reading, attempt to find what is being discussed within one’s self.
Experiment if needed, to uncover / unveil it… while continuously observing inner self.

best wishes everyone

Good eye and good point.
Esoteric writing is present in all languages.
Living or dead.
