We would also like to dedicate this learning for the speedy and complete recovery of our friends' 5-year-old son, Joseph Benjamin, son of Ireneusz Khrystof, diagnosed in April with ALL leukemia. Please have him in mind when studying.
p. 28 Chapter Nine
5. A person who puts on his tallit kattan and recites a blessing over it, when he goes to the synagogue and puts on his tallit gadol he must say another blessing, as the walk from his house to the synagogue is considered an interruption. If he prays at home and has in mind when reciting the first blessing that it should also include the tallit gadol, and in the meantime he does not interrupt by talking or with other matters, he does not recite a new blessing. (Shulchan Aruch 8)
