Based on the story of the man from Bandra, what is the prescribed method for using Udi to overcome personal troubles like bad dreams?

According to the experience of the gentleman from Bandra detailed in Chapter 35, the method for using Udi to resolve personal afflictions involves both a physical application and a mental disposition. A Sai devotee gave him specific instructions which proved to be highly effective. The method described involves three key steps: First, 'apply a little [Udi] to your head' when going to sleep. Second, 'tie a packet and keep it under your pillow.' Finally, and most importantly, one must 'remember Shri Sai in your mind' and 'keep devotion in your heart.' Chapter 35 emphasizes that this combination of applying the sacred ash, keeping it close, and maintaining faith in Sai is what allows the Udi to manifest its 'natural tendency' to immediately remove trouble and bring peace, as it did for the man who was then able to sleep soundly.
