Does Baba teach that we should not make any effort for spiritual growth, trusting that God will provide everything?

No, Baba makes a clear distinction between material needs and spiritual progress. Chapter 19 clarifies the saying, "If my Hari exists, he will give me while I am on my bed." Baba explains that this truth applies only to worldly provisions like food and clothing. He strongly cautions against applying this to spiritual matters, stating that doing so will cause one to lose spiritual wealth completely. For spiritual success, Baba's priceless words are the guiding principle: "As one sows, so shall he reap." This emphasizes that personal effort is essential for spiritual advancement.
