Leaving Eretz Yisrael #4

In the summer of 5674, Maran Ha-Rav Kook was invited to the Agudat Yisrael conference in Germany, and he was in great doubt whether he should attend. He wrote in his letters how difficult it was for him to agree to leave Eretz Yisrael, even temporarily. At the same time, there was great potential to influence the Rabbis of the Agudah to support the revival of the Nation of Israel in its Land (Igrot Ha-Re'eiyah, igeret #678).
Our Rabbi, Ha-Rav Tzvi Yehudah, believed that it was important to attend (Tzemach Tzvi #23) and even sent background information (Igeret #684), but it was still difficult for Maran Ha-Rav to come to a clear decision (Igeret #687, #691). In the end, he decided to attend, but with much inner turmoil (Igeret #694).
Our Rabbi explained that Maran Ha-Rav did not agree to leave Eretz Yisrael, even temporarily, as per the request of the administration of Agudat Yisrael to participate in the Kenesiyah Gedolah in Frankfurt am Main and in the Council of Torah Sages, until added to this were doctors' orders that he required a medical procedure outside of Israel (Le-Shelosha Be-Elul, p. 25). Maran Ha-Rav's wife also traveled with him to visit well-known doctors for her own health-related issues (Igeret #695). They arrived at the end of Tamuz 5674, and World War One broke out on Tisha Be-Av. The conference was canceled, and they were unable to return to Israel for four years. But that is a different story…
