I have found a wonderful true story where a young Jewish scholar learns from one of the most illustrious rabbis what profane behavior toward the sacred has in its true effects. Read it to understand.

A Tzaddik's Tear
By Yerachmiel Tilles
About 30 years ago, an American rabbi visiting Miami, Florida gave a lecture on the life and accomplishments of the famed "Chafetz Chaim" (Rabbi Israel Meir HaCohen Kagan, 1838-1933). He described the life of the great sage who lived a humble life as a shopkeeper in in the village of Radin, in Poland, yet was recognized throughout the Jewish world as a great scholar, tzaddik (righteous person) and leader.
There was another story the rabbi wanted to tell, but he hesitated, for he only knew part of it. As he stood at the lectern, he thought for a moment and then decided that he would tell it anyway. He rationalized that even an unfinished story about the Chafetz Chaim would have a meaningful message.
He began to relate an incident about a teenage boy in the Chafetz Chaim's yeshiva who was found smoking a cigarette on Shabbat -- the sacred day of rest. The faculty and student body were shocked, and some of the faculty felt that the boy should be expelled. However, when the Chafetz Chaim heard the story, he asked that the boy be brought to his home.
At this point, the rabbi interrupted the narrative and said, "I don't know what the Chafetz Chaim said to the boy. I only know that they were together for a few minutes. I would give anything to know what he said to this student, for I am told that the boy never desecrated the Shabbat again. How wonderful it would be if we could relay that message -- whatever it was -- to others, in order to encourage them in their observance of Shabbat." The rabbi then continued with his lecture.
After his talk, the hall emptied of everyone except for one elderly man, who remained in his seat, alone with his thoughts. From the distance, it seemed he was trembling, as if he was either crying or suffering from chills. The rabbi walked over to the elderly man and asked him, "Is anything wrong?"
The man responded, "Where did you hear that story of the cigarette on Shabbat?" He did not look up and was still shaken. "I really don't know," answered the rabbi. "I heard it a while ago and I don't even remember who told it to me." The man looked up at the rabbi and said softly, "I was that boy." He then asked the rabbi to go outside, and as the two walked together, he told the rabbi the following story:
