A man rushed into shul to hear "Kedusha." In the process, he stepped on a another man's shoes and made them dirty. After the prayer, Reb Yisroel asked the man over to a corner of the shul. In private, he told him he must apologize to the other man. Although Kedusha is a great mitzva, any mitzva is canceled if doing it harms another person.
love your neighbor, love Hashem
While it is important to be diligent and righteous in our service to Hashem, we must temper that also with serving those around us and showing them love and deference. Our concern for the needs of others, for the time of others, must be at the forefront of our minds as we endeavor to show love to our Creator and His creation.
