Sat-darshana Bhashya (translation)

Verse 14.

निद्रा न विद्या ग्रहणं न विद्या
गृह्णाति किञ्चिन्न यथार्थबोधे ।
निद्रापदार्थग्रहणेतरा स्यात्
चिदेव विद्या विलसन्त्यशून्या॥

Insensibility is no knowledge, nor is apprehension of objects seen.
Nothing is seen in awareness supreme.
Different from both is consciousness there.
No void is that-the knowledge, luminous and true.

Insensibility or a state of sleep in which there is no sense-activity is no knowledge. It is an established fact that in the consciousness of the self, nothing is seen as separate from or outside of itself, and an ignoramus may mistake such a state for perfect oblivion, a complete non-recognition of objects. To remove this misconception it is stated that Self-knowledge Atmajnana is no insensibility. Nor is it apprehension of objects seen. This is a knowledge indeed, but a knowledge of the known as differentiated from the knower. True knowledge is different from both of these, yet it is consciousness that lends its light to the duality of knowledge and ignorance. It is ’luminous’, not inert, or indifferent to the duality, dvandva, though it is different from the relational knowledge and ignorance.

The next verse gives the analogy of gold in ornamental forms to make clear that Truth is consciousness and One alone, and that the different forms of it are not really separate from their original, the one Substance.
