Why does mental disease exist? — Avadhuta Gita

Following is an excerpt from a samvaad (dialogue) session with Acharya Prashant.

Question: The Avadhuta Gita says, “svarupa-nirvanam anamayoaham” (My Nature is Freedom, there is no Maya to me), then why do we get hurt? Why do we get sick?

Acharya Prashant:

The fundamental does not get hurt and the fundamental does not get sick.
