A young Breslover Chossid, not the superficial-external-funny-dressing-type but a deep, sincere, intense servant of Hashem, was lying on his death bed. He was surrounded by his friends and the atmosphere wasn't, may we say, at the peak of Mitzvah Gedola Li-hiyos Bi-Simcha Tomid.
The sick young chossid, who was at the bein hashmashos between the world of falsehood and the world of truth, looked at his friends and broke out into a huge smile. "You know my beloved friends, there is nobody on earth happier than I. I'm connected to "Rabbeinu!!!" [Rebbe Nachman].
He and his friends started to sing עז והדר לבושה [you know the tune...]. They sang and sang for six consecutive hours [!!] until he returned his pure soul to his Maker.
[From Bi-sod Siach gimmel iyar 5772]
