। ॥ २८२ ॥
In plain words
Through scripture, through reasoning, and through your own direct experience, know that your Self is the Self of everything. And wherever a false superimposition still lingers, clinging on because of mere appearance, remove it.
Close to the Sanskrit
Having known, through scripture, reasoning, and one's own direct experience, the universality of the Self [as the Self of all], accomplish the removal of the self-superimposition that has, in some instance, been acquired due to [mere] appearance.
