Baha'u'llah's half brother, Mirza Yahya, also known as Subh-i-Azal, arrived in Ba_gh_dad, and soon afterwards differences, secretly instigated by him, began to grow, just as similar divisions had arisen among the disciples of Christ.

These differences (which later, in Adrianople, became open and violent) were very painful to Baha'u'llah, Whose whole aim in life was the promotion of unity among the people of the world.
Two Years in the Wilderness About a year after coming to Ba_gh_dad, He departed alone into the wilderness of Sulaymaniyyih, taking with Him nothing but a change of clothes.

Regarding this period He write in the Book of Iqan( 13) as follows:-- In the early days of Our arrival in this land, when We discerned the signs of impending events, We decided, wilderness, and there, separated and alone, led for two years a life of complete solitude.

From Our eyes there rained tears of anguish, and in Our bleeding heart there surged an ocean of agonizing pain.

Many a night We had no food for sustenance, and many a day Our body found no rest.
