What specific instructions did Sai Baba give to the devotee who was massaging his feet, and what was the immediate effect of his words?

According to Chapter 27, when a lady was serving Baba by massaging his feet, he was pleased and offered her words of welfare. He instructed her, 'Rajaram, Rajaram, say it with your tongue. Keep saying this daily; O mother, your life will be successful; your mind will become peaceful, and you will achieve immense welfare.' The text emphasizes the power of these words, stating they 'go and pierce the heart.' It describes this moment as a transmission of power, or 'shaktipat,' performed in an instant through the 'yoga of words,' demonstrating how he could fulfill a devotee's desires and achieve their welfare so compassionately.
