Brahman (being infinite) cannot be excluded (separately perceived). It being infinite, nothing can be added to it. It being unattached, it is not the support of anything and it is not supported by anything. It is one alone and non–dual. There is no plurality whatsoever.
Annotation
Brahman being infinite, nothing can be taken away from it nor added to it. This is similar to the expression heya–upādeya–varjitā in the Lalita Sahasranama. Similarly, Brahman is neither the ādhāra nor ādheya of anything. If we take water in a vessel, the vessel is the support (ādhāra) and water is the supported (ādheya). This is possible in finite objects. Brahman being infinite and unattached, there cannot be any concepts of supporter and supported in It.
