The bracha that one makes when seeing a chocham: May it only be said on a particular chocham only once, or may it be said so as long as 30 days have passed since seeing the chocham?
Answer:
If thirty days have passed, the berachah can be recited upon seeing the same chacham again.
This is a universal principle that applies to all birkos re’iyah (Shulchan Aruch 224:13).
