The characteristic of space is to give room to or accommodate the other substances.
Space is divided into two parts: The dimension of Lokakasha is fourteen rajlok or rajju, however Alokakasha is infinite.
[6] That portion of space in which all the substances are found is called the universe (lokakash).
At the summit of the lokākāśa is the Siddhashila (abode of the liberated souls).
[10][11] The (empty) infinite space outside the universe is called the non-universe (alokakash).
