As we say ‘Daivam Maanushya Rupena,’ we will see God in every Human Being. Every one is a God. Man minus ego is God. If you become aware about presence of God with in you and also the presence of same God in others, then peace and joy you get is immense and unequaled. So, Satya Sai Baba quotes that he is just a manly form of God. To spread the message of Love and Godliness, every now and then Messengers of Almighty appear on Earth.
If Shirdi Sai Baba was the first Avatar, Second was Satya Sai Baba and the Third to come is Prema Sai Baba. All three godly men will be born in Bharadwajasa Gotram with either ‘Shiva’ or 'Shakti' Amsha. Before the soul of Shirdi Sai Baba departed from his body in 1918, the last sermon was about his re-birth in two more Avatars (Satya Sai Baba and Prema Sai Baba). Devotees of Sai say that Shirdi Sai Baba intimated to be born as Satya Sai Baba in Andhra Pradesh and Prema Sai Baba in Karnataka.
Exactly eight years after the death of Shirdi Sai, we had the birth of Satya Sai in 1926. If one believes in Satya Sai, then his next form is already in making with name of Prema Sai to be born win Bharadwajasa Gotram with Goddess Shakti Amsha.
The first mention of Prema Sai by Satya Sai Baba appears to be in the discourse "Shiva Shakthi, 6 July 1963." It is a conversation between Shiva, Shakthi, and Bharadwaja. After Bharadwaja performed a ritual, Shiva said that they would take human form and be born in the Bharadwajasa lineage, thrice: Shiva alone as Shirdi Sai Baba, Shiva and Shakthi together at Puttaparthi as Satya Sai Baba, and Shakthi alone as Prema Sai, later.
Finally Satya Sai states, "There will be Prema Sai who, one year after the passing of the Satya Sai form will be born in Karnataka (the old Mysore State), at a place between Bangalore and the city of Mysore."
