If the bondage of the soul is due to Avidya or ignorance only, final liberation is possible. But if the soul is really bound, whether the soul be regarded as a certain condition or state of the Supreme Soul or Brahman, as stated in Sutra 27, or as a part of the Supreme Soul, as expressed in Sutra 28 - its real bondage cannot be destroyed. Thus the scriptural doctrine of final liberation becomes purposeless and absurd. If the difference is real it can never come to an end. All the scriptural instructions with regard to the final emancipation will be meaningless.
Bondage is only the idea of separateness.
If separateness is real there can be no final release at all. But if the difference is due to nescience or ignorance, then knowledge of Brahman or Brahma-Jnana can annihilate it. Then the Supreme Reality or Brahman, the non-difference may be realised. It cannot be said that the Sruti equally teaches difference and non-difference. The Sruti aims at establishing non-difference only.
