Rav Hirsch to Rabbi Tzvi Hirsch Kalischer

"My mind is too small to recognize the good and truth that will result, according to you, from your efforts in colonizing Eretz Yisroel. What you consider a mitzvah and a great obligation, does not seem so in my humble opinion. I have no knowledge of secret matters, and I see nothing better than to continue on the road paved by our fathers and predecessors, who made it their goal only to improve our Torah observance, and to look forward to the redemption, which might come any day, if we only listen to G-d's voice. They never approached redemption through the improvement of the Holy Land, only through the improvement of our hearts and deeds." Rav Hirsch to Rabbi Tzvi Hirsch Kalischer, 1864  (Shemesh Marpei, p. 211)
