Hi, I'm Sarah Batty, religious sage (9)

I believe the answer is:

maharishi

I'm a little stuck... Click here to teach me more about this clue!

'religious sage' is the definition.
'maharishi' can be an answer for 'sage' (I've seen this before). I am not certain of the 'religious' bit.

'hi i'm sarah batty' is the wordplay.
'batty' indicates an anagram.
'hi'+'im'+'sarah'='hiimsarah'
'hiimsarah' anagrammed gives 'MAHARISHI'.

Can you help me to learn more?

(Other definitions for maharishi that I've seen before include "Indian sage" , "leading teacher" , "Religious teacher" , "Teacher of Hindu mysticism" , "Hindu spiritual leader" .)

I've seen this clue in The Independent.
