Q. One of the Gedolei Hador came to my neighbourhood and his Schachris minyan, was conducted in a house and open to the public. Is it better to daven in my Makom Kavua (establihed place) in Beis Hamedrash, or in the house with the Gadol?
Once one attended the Gadol’s minyan once or twice should he go back to davening in his Beis Hamedrash or rather continue davening by the Gadol?
A. Horav Shlomo Miller’s Shlit’a opinion is that it is permitted to daven with the Gadol Haddor.
As far as continuing extensively depends on other factors such as the spiritual benefits attained and a Rov familiar with the situation should be consulted.
