Are you the witness of the witness?

The following excerpt is from a samvaad (dialogue) session with Acharya Prashant.

Question (Q): Acharya Ji, once I had the experience of the ‘seer’, but it remained only for few minutes. How can I be the seer forever?

Acharya Prashant (AP): And you are the seer of that ‘seer’, now that you are talking about it.
