Chidakasha Gita Pdf May 2026

I need to verify if "Chidakasha Gita" is part of traditional Hindu scriptures. The term "Chidakasha" is related to Advaita Vedanta, where the inner space is considered the mind's realm, distinct from the external world. Maybe the "Gita" here is a collection of teachings on this concept. However, I don't find any primary references to such a text in major Hindu scriptures or well-known commentaries.
