you are right, hindus are meaninglessly trying to find some root for their religion while there is no root for this religion.
you will be hindu no matter what. just worship any one out of 33000000 or even dont worship any one...
any way this number is still counting as Sai Baba has alreay included and Ajmer Shareef is also in the number... so no root is there, no base is there. just worship or even dont worship and you will remain the hindu and hindu only....
