In the early summer of 1923 Shoghi Effendi again left Haifa and sought some restoration of health and solace in the solitude of the high mountains of Switzerland. But, unlike later years, when he continued to keep in constant touch with the work of the Cause by cable and letter, this was once more a complete break, a fleeing into the wilderness, a soul-searching, a communion with himself and his destiny in order to find the strength to go back and assume the duties of his high office … [until] he was returning “after a long and unbroken silence” to take up once again “my work of service to the Cause of Bahá’u’lláh”.
