Baba's first women mandali stayed in the Post Office building from the end of 1924 until the end of 1926. The large verandah to the east and south was used for gatherings and sometimes for school classes for boys or girls. At that time, a large compound was created with bamboo matting to the north to provide privacy. This compound contained toilets and a kitchen where the women would do their cooking for the colony, which often numbered in the hundreds then.

During the second long stay at Meherabad, the Post Office was used as quarters for family groups, and later Baba kept His disciple Pleader fasting in seclusion here for many months.

The Post Office was special and significant to Mehera because it was here on May 19th 1923, that she first bowed down to Baba and He told her family not to force her to marry. It was also here that Baba revealed to Mehera her role as His Beloved.

Near here, Babajan and Meher Baba had their meeting of silent communion. When Babajan came to Meherabad on April 1st 1928, she stood on the path near the Post Office as Baba came down the Hill and stood on the west side of the railroad tracks.
