Gulzar Dadi

Om Shanti,

but I want to how and when the BKs knew that Gulzar Dadi is the person through which Shiva will start it's Avyakt Murli? When on which year was the first avaykta Vani was conducted?

And what is current age of Gulzar Dadi?

Dear Rahul,
Omshanti. The first Avyakt Vani was narrated through Gulzar Dadiji on 21st Jan, 1969. It is generally told that after the cremation of Brahma Baba, all the BKs were sitting in meditation in the Pandav Bhavan and at that time Avyakt BapDada entered into her and started narrating Avyakt Vani. But it is not known whether she was sitting in the audience or on the sandhali.
I am not aware of her present age, but you can find out from the BK literature.
