Seems to us aakaasha is identical or at least next to, with Dark Energy.
Dark Energy, aakaasha*, is almost impossible to detect, because it "shines" (verbal root kaash = shine) "inwards/backwards" (aa-)?? (The verbal prefix aa reverses the meaning of verbs of giving and going [Macdonell]; e.g. gam, to go; aagam, to come) * (brahma[n]** is) aakaashas tallin.gaat -- brahma-suutra ** from the root bRh, to grow, expand (like DE makes the universe to)??
