על ומשלם ‘ה נצר אמונים חסידיו כל ‘ה את אהבו” (כד לא) “גאוה עשה יתר
The Maggid of Brod, Rav Moshe Osterer, explained: In Maseches Brachos (30a), the Gemara brings three opinions about what a person should be strict about if he wants to be a chassid: Rav Yehudah says he should be careful regarding matters of nezikin, damages. Rava says he should fulfill what it says in Maseches Avos, and some say he should be careful regarding brachos. We can easily understand why distancing oneself from causing damage to another, and being strict about the ethics stated in Maseches Avos are acts of chassidus. But what is especially pious about being careful when reciting brachos?
The meaning of the Gemara is that a chassid in brachos is someone who is strict to make his brachos specifically in the ears of someone who will answer amen after them. By doing so, he merits to complete and fulfill his brachos. This is the kavanah of this passuk as well: “Ehevu es Hashem kol chassidav” – according to all three opinions brought in the Gemara, among them he also warned about brachos, on condition that he is shomer “emunim,” meaning he is strict to recite the brachos in the ears of someone who will answer amen after them. He can then be called a chassid because “notzer Hashem” his merit for the answering of amen of the listeners as well, and that is what completes his brachos. (Darash Moshe)
