The birth and parentage of Shri Sai Baba was wrapped in mystery. He had always eluded such questions. But once a strange situation warranted a legal statement from him. A commissioner was sent to Shirdi for the purpose of taking down the evidence from Sai Baba. The course of statement followed like this: 

Commission  What is your name?
Baba :  They call me Sai Baba. (Sai was not a personal name but an epithet)
Commission  Your father’s name?
Baba :  Also Sai Baba. (It implied that His descent or divine advent is not conditioned by human parentage)
Commission  Your Guru’s (Master’s) name?
Baba :  Venkusa.
Commission  Your creed or religion?
Baba :  Kabir. ('Kabiri’ means the perfect mastery. There was a Perfect Master called Kabir whose followers are known as Kabir Panthi.)
Commission  Caste or Community?
Baba :  Parvardigar. (The Almighty)
Commission  Age?
Baba :  Millions of years. (It implied that He existed always).
    Baba further mentioned
    "I know everyone
    I live with everyone
    All are mine and
    Everything is mine"
    (Which implied the gnosis of ‘I am God’)
It was interesting to note that Sai Baba was not asked to sign his statement. He had no name to sign.
