The meaning of this Bandish:

Jiyaa Maanata Naahee

The mind finds no peace; restlessness persists day and night.
Without seeing the beloved (or divine), every moment feels uneasy.
The singer expresses deep inner pain — not knowing whom to share it with.

Bhagavad Gita Connection - Chapter 2, Verse 66

अशान्तस्य कुतः सुखम् ॥

For the restless mind, there can be no happiness.

Connection

Bandish: “Chain na aavat… akulaave” (no peace, constant restlessness)
Gita: Without inner calm, happiness is impossible

Both express the state of an unsettled mind longing for peace (or union).
