Bliss of Hindus, those at the front welcomed by circulating rani (7)
I believe the answer is:
nirvana
'bliss' is the definition.
(blissful state in Buddhism)
'the front welcomed by circulating rani' is the wordplay.
'the front' becomes 'van' (I've seen this before).
'welcomed by' indicates putting letters inside (letters welcomed inside).
'circulating' indicates anagramming the letters.
'rani' with letters rearranged gives 'nira'.
'van' going into 'nira' is 'NIRVANA'.
'of hindus those at' acts as a link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for nirvana that I've seen before include "Buddhist paradise or hereafter" , "State of pure happiness" , "State of perfect happiness" , "Transcendent state of Buddhists" , "religious ecstasy" .)
