Language includes Hindu mantra for DIY drink (4-4)

I believe the answer is:
home-brew
'drink' is the definition.
(home brew is a kind of drink)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for home-brew that I've seen before include "perhaps of Attic origin?" , "Domestically-produced beer" , "DIY beer" , "One's own beer?" , "moonshine?" .)
