Band in blissful state (7)
I believe the answer is:
nirvana
I believe this is a double definition.
'band' is the first definition.
(I've seen this before)
'blissful state' is the second definition.
(I've seen this before)
'in' acts as a link.
(Other definitions for nirvana that I've seen before include "Hindu or Buddhist blissful meditative state" , "religious state" , "The Buddhist's version of Paradise" , "'Transcendent state, the final goal of Buddhism (7)'" , "Ultimate state in Buddhism" .)
