Bahá’u’lláh could trust ‘Abdu’l-Bahá with the most difficult of tasks as He knew He would never waver. One such task was that of building a Shrine for the Báb on Mount Carmel, above what was then the small town of Haifa, facing the Mediterranean Sea. One of many obstacles which developed was the owner of the plot, influenced by scheming Covenant-breakers, would not readily consent to sell the land. ‘”Every stone of that building, every stone of the road leading to it,” He, many a time was heard to remark, “I have with infinite tears and at tremendous cost, raised and placed in position.” “One night,” He, according to an eye-witness, once observed, “I was so hemmed in by My anxieties that I had no other recourse than to recite and repeat over and over again a prayer of the Báb which I had in My possession, the recital of which greatly calmed Me. The next morning the owner of the plot himself came to Me, apologized and begged Me to purchase his property.”’

A companion of ‘Abdu’l-Bahá on His journey in America recorded a moment when the Master expressed His anxiety for the future: ‘I am bearing these hardships of traveling so that the cause of God may push on unconstrained. For I am anxious about what is going to happen after Me. Had I had ease of mind on this score I would have sat comfortably in one corner. I would not have come out of [the] Holy Land… I fear after Me self-seeking persons may disturb again the love and unity of the friends.’ The Master talked in sorrowful tones until the automobile stopped at a hotel in Chicago.

In reading over my diaries - so very little of which I have quoted out of hundred of pages written off and on throughout the years - it seems strange to me there is practically no reference to the World War raging everywhere during almost six years and constituting such a dire threat to the safety of the World Centre of the Faith and particularly to the Guardian himself as Head of that Faith. Nothing could more eloquently testify to the internal upheavals he was going through during all those years than this blank. The day-to-day pressures and the work, worry and mental exhaustion were so great that it crowded mention of this constant threat and anxiety into the background.
