What were Baba's instructions on how to interact with different people and beings?

In Chapter 3, Sai Baba gives specific advice on social conduct. He strongly warns against associating with people who have 'abandoned religious conduct' and have a fallen character, advising one to move aside and not even stay in their shadow, considering them very dangerous. Conversely, He also taught universal acceptance by stating that no one comes to Him without a prior connection. Therefore, one should not 'shoo away anyone, be it a dog, pig, or fly.' The core instruction underlying this was for the devotee to perform His service with devotion, through which the 'God of Gods' would show mercy and an eternal treasure would be found.
