Sai Baba had made a mosque at Shirdi, His durbar. He said, 'This is not a mosque. It is Dwaraka.' It is Dwaraka Mayi (Dwaraka Mother) or Masuda Mayi (Musjid Mother), for it saves, it helps, it grants all favours. Dwaraka means a place whose four gates are open to the four castes, to grant the four Boons to the four types of aspirants. Since Sai Baba has come again as promised, He has now the Dwaraka, called Prashanthi Nilayam, which welcomes the religious of all castes, and even the irreligious! It confers the Four Boons: Dharma, Artha, Kama and Moksha, to the four types: Aartha, Arthaarthi, Jijnasu and Jnani, with as much love and as much consideration as at Dwarakamayi.
Consistent with the name Dwaraka-vasin, Sai Baba planned to install a Krishna Image at Shirdi, but He left, before it could be done there.
Now, to demonstrate that Prashanthi Nilayam is again the Dwaraka Mother, and that He is the Dwarakmayi Vasin (the Resident of Dwarakamayi) Sathya Sai Baba has installed a Krishna on the porch, another on the altar, a third in the prayer hall and a fourth, overlooking that hall itself.
