'blissful?' is the definition.
Both the answer and definition are adjectives. Maybe you can see an association between them that I can't see?

'can holy wars' is the wordplay.
'wars' indicates anagramming the letters (I've seen 'warring' mean this).
'can'+'holy'='canholy'
'canholy' anagrammed gives 'HALCYON'.

'be' acts as a link.

Can you help me to learn more?

(Other definitions for halcyon that I've seen before include "Tropical kingfisher" , "undisturbed" , "Prosperous" , "Calm and peaceful" , "Serene" .)
