What about his teachings and his life made you decide that he is Avatar?
His teachings. I could fill a book of commentary. But here are a few examples:
I could not accept the classic dogma of Western religions which seemed to me to be not justifiable if there was a loving God. There is no true balance in that view. The Eastern view which Meher Baba stated clearly is one of reincarnation and karma. His map of the journey of the soul from creation to realization is one with evolution is a necessary part.
His comment an atheists, for example struck me as true and has affected me strongly:
From my point of view, far more blessed is the atheist who confidently discharges his worldly responsibilities, accepting them as his honorable duty, than the man who presumes he is a devout believer in God, yet shirks the responsibilities apportioned to him through Divine Law and runs after sadhus, saints and yogis, seeking relief from the suffering which ultimately would have pronounced his eternal liberation.
His
colophon shows the major world religions as all valid paths and is another way of expressing the Blind Men and the Elephant story.
His life: Given what I know of typical religious and apparent spiritual teachers, I am well aware of how often they are motivated by lust for power, sex, greed and the desire to have many disciples. There were many many incidents I read about none of which betrayed the slightest hint of such motivation.
Here's one example. There was an auto accident in India where Meher Baba was injured badly and was in pain for the rest of his life.
Baba was bathed in blood, his tongue was torn, his hip bone fractured, and he had abrasions on his forehead, nose, cheeks and legs. His reaction?
"The whole thing happened in the flash of an eye. When I came to, I found I was the only one in the back of the car. I stepped out and went to the front to see how Baba was and saw him reclining in the front seat, with blood on his clothes and face. [ Even though Baba was bleeding ], never in my life have I seen such utter radiance and luster as was on Baba's face then! He was like a king, a victorious king who had won a great battle. Lord Krishna must have looked like that in his chariot on the victorious battlefield. The radiance was blinding! I could see nothing else, not the car, nor the surroundings, only Baba's face in glorious triumph!
After a few moments, Vishnu asked Baba if he was hurt much. Baba nodded, pointing to his mouth and leg, but gestured for Vishnu first to see how the others were."
The Avatar: At the end, I knew he was no ordinary human. His statement in the same place where he noted honorable atheists included
I am neither a mahatma nor a mahapurush, neither a sadhu nor a saint, neither a yogi nor a wali. He asserted that he was the Avatar in that document.
The final step for me was to go to India and to meet his close disciples who were alive at that point. I found them to be utterly down to earth and very different people in their opinions, dress and personality. They all were very loving while at the same time being strongly individual. It was like all the crap that we all (including me) carry around had been burned off leaving real human beings.
At the end of all of this, I was able to say "Meher Baba is the Avatar"
I hope this answers your question!
