If I can't find information on a specific holy person, what should I do according to Sai Baba's philosophy?

According to the philosophy shared in Chapter 19, the recommended path is to focus on the underlying principle of devotion rather than a specific name. The text advises that 'Allah-Malik' (God is the Master) is the ultimate protector. The emphasis is placed squarely on one's own spiritual effort and sincerity. As Chapter 19 states, 'As the action, so the hearing; as the practice, so the benefit.' A personal account in the chapter illustrates this by showing how simply nurturing a 'wave of good thoughts,' like chanting a divine name, leads to great satisfaction and peace. Therefore, you should continue your practice with firm resolve, knowing the benefit comes from the practice itself.
