"The Tzemach Tzedek commented: Such an interpretation could be proposed only by a chassid who has davened and labored in avoda for thirty years." (Hayom Yom 29 Adar 1)
Gosh we don't even know what that means, to labor in avoda for thirty years. Well, I can only speak for myself, I guess. I don't even know what that means. Thirty minutes is more in my mind frame.
