8. Uncompounded space here is defined as a lack of obstructive contact. It is not the type of space one finds in a hole or an empty glass, but the abstract concept of space that can either be occupied by material objects or not. The Vaibhāśika assertion is that space, so defined, is truly singular and permanent, unaffected by the movements of objects within space. Śāntaraksṃita argues that it does not make sense to describe pervasive uncompounded space as unitary since it has relations with other entities in various directions. If that is the case, then there are parts, and uncompounded space is not inherently singular. Nothing with parts is inherently singular or unitary.
