The fundamental element of the cosmos is Space. Space is the all-embracing principle of higher unity. Nothing can exist without Space. .. According to ancient Indian tradition the Universe reveals itself in two fundamental properties: as Motion and as that in which motion takes place, namely Space. This Space is called Akasa .. derived from the root kas, 'to radiate, to shine', and has therefore the meaning of ether which is conceived as the medium of movement. The principle of movement, however, is Prana, the breath of life, the all-powerful, all-pervading rhythm of the universe.
