Matter is the only form of energy which hold consequences and therefore importance. Other forms of energy can be equated to properties of matter. All properties (processes (verbs and abstract nouns), qualities (adjectives and adverbs), and relations (function words) do not have existential status.
Ultimately, we are dealing with matter (objects) in the end, and not dealing with concepts directly, only dealing with matter that instantiate the properties of the matter as concepts.
