In plain words
Passages speaking of 'Space' serve to guide meditation by pointing to the defining mark of Brahman. Space is well known in the sacred texts as the Self, bodiless and subtle like the open sky. It is the very power that sustains, bears, and unfolds names and forms—those seeds of the universe resting in their own nature, just as foam rests upon water. Brahman resides within them, yet remains untouched by any name or form. Transcending all limitations while upholding them, this is the true nature of Brahman.
Close to the Sanskrit
Expressions such as 'Akasha' are for the purpose of indicating the characteristics of Brahman for meditation. Akasha is indeed well known in the Vedic texts as the Self, resembling space due to its bodilessness and subtlety. And that same Akasha is the sustainer, bearer, and manifestor of name and form, which rest in their own self as the seeds of the world, like foam in water. That Brahman exists between those name and form, and between those names and forms is that which is untouched by names and forms; thus that Brahman is distinct from names and forms, untouched by names and forms, and yet the sustainer of them—such is the meaning of Brahman.
