From a BK circular provided by Sister Jannisder in another thread:
We are also preparing for the dedication ceremony of 'Prakash Sthamb (Tower of light), memorial for Dadi Prakashmaniji, on 25 August, 2008, which marks the first anniversary of our beloved Dadiji's ascension to the Subtle Region. The monument seems to be the most befitting tribute to our Dadiji. All of you are heartily invited to attend the ceremony (in person or subtle form) and fill your intellects with Dadiji's love and power, just as Dadiji used to envelop all of us in her embrace...
If the BKs believe that Dadiji has ascended to the Subtle Region then what about the Bhog messages that spoke of her rebirth? Or is it an anniversary of her short stay in the Subtle Regions before taking rebirth (as believed by BKs)?
If BKs from all over the world attend the dedication ceremony of the memorial for Dadiji either in person or through subtle form, then what about the Shrimat that says we should remember none but one Baba?
