Based on the provided text, what philosophy did Sai Baba express regarding love, devotion, and worldly attachments?

The account of Ratanji's visit in Chapter 14 reveals Sai Baba's profound spiritual philosophy. His practice of asking for Dakshina was a method to teach detachment from worldly wealth. He articulated his own detachment by saying, "In the world, someone belongs to someone... but here, no one is ours; our only one is Allah." This shows his focus was entirely on the divine. Furthermore, Baba emphasized the immense power of sincere devotion. He stated, "I lack only the one who loves Me as his very life; if he gives Me one quality, I give him a hundred qualities in return." This highlights a core principle of his teaching: a small act of pure love and surrender towards the divine is met with an overwhelmingly generous and hundredfold reward.
