Sai Baba used to say that he practiced Guru Yoga, complete attention on the teacher. Baba would mention his Guru, a man called Venkusha who lived in the Nizam’s provinces in Andhra Pradesh, closer to Maharashtra. He was the zamindar of that province. In his youth, Baba lived with this person, Venkusha, for sometime and all the sadhana he did was to sit and look at His Guru wide-eyed and nothing else. He said that he looked and looked and looked! He also listened to what was taught to others.
