The space of consciousness, by its nature, is empty, one, without a second

Cid-ākāśa — the space of consciousness — is one of the Vāsiṣṭha’s most original concepts. It is not consciousness as a quality of the subject, nor consciousness as a state, but consciousness as space: the medium in which everything appears, the emptiness that contains all forms without being affected by them. It is śūnya in the sense of “without intrinsic content” — not in the nihilistic sense of “nothing.” And it is ekam ananyadhīḥ — one, without a second to accompany it. The entire Advaita doctrine condensed into three words.
