There is a declaration of the Shrutis that is ever Nature does succeed in knowing the twenty fifth, she then becomes at one with the Individual Soul who is united with her. On account of this Individual Soul or Purusha, who is not manifest and which in his real nature is not subject to changes, comes to be called as the Unawakened or Ignorant.
बुध्यते यदि वाक्यक्तमेतद् वै पञ्चविंशकम्। बुध्यमानो भवत्येव सङ्गात्मक इति श्रुतिः। अनेनाप्रतिबुद्धेति वदन्त्यव्यक्तमच्युतम्॥ अव्यक्तबोधनाच्चापि बुध्यमानं वदन्त्युत।
