The second impediment is more interesting. Baba had both Hindu and Muslim features in his body and in his actions and practice, and, HIS mission in life was to unify Hindus and Muslims into one compact mass with common religious, spiritual and worldly interests.
As he had a Hindu Guru, namely, Gopal Rao Deshmukh alias Venkatesa or Venkusa, he was considered fitted to guide his Hindu followers.
In order to guide his Muslim followers, initiation into Islamic scripture by a Maulana was essential according to public opinion. So, his destiny had to be fulfilled by his getting a second Guru, a Muslim. Jawar Ali Maulana was a distinguished Maulana of the last century, residing for some time at Rahata. He had extraordinary ability and learning, but had disagreed with his Rahata followers.
He came to Shirdi and noted that Baba had a large Hindu following who worshipped him at the Mosque. He called upon Baba to come out of the Mosque and asked him whether he knew the Koran and the Shariat. Baba had learnt neither.
So Jawar Ali Maulana ordered him to accompany him to Rahata and there Baba was living with this Guru for about two months. The Guru initiated him into the mysteries of Islamic spiritual literature.
Baba did humble seva to this Guru, carrying water pots, fetching faggots, lighting up fire, doing hard physical work, which others would complain of. But in the case of Baba, he accepted his position as the sishya of Jawar Ali with perfect sincerity and underwent with sweet complacency, all the ordeal and the course of training given to him.
The villagers of Shirdi, headed by Mahlsapathy who were very anxious to have Baba back again permanently settled at Shirdi, requested the Maulana to allow them to take Sai Baba with them. This was agreed to by the Maulana on the condition that with Baba he also should be taken to Shirdi, and that both he and Baba should be fed and supported by the villagers of Shirdi. So both came and lived at the Shirdi Mosque.
Some time later, Jawar Ali was drawn purposely into a dispute with Devadas, a noted Hindu saint living in a chavadi at Shirdi, and Devadas’s questions cornered Jawar Ali. The latter had to make so many admissions that the surrounding spectators were moved to laughter. Jawar Ali resenting this humiliation left Shirdi and did not return there for long years to come.
Baba’s worship at the Shirdi Mosque went on and gathered strength. What appeared as the second impediment tended only to increase the devotees’ attachment through Viraha and admiration and helped Baba’s mission. It must be noted here that the worship mentioned here is individual worship, each one going to Baba and placing flowers on his feet and treating him as God, Avatar or Guru.
