Based on the teachings, what is the prescribed path to salvation, and how does a person's spiritual progress benefit others?

The path to salvation, as detailed in Chapter 17, is referred to as the "knowledge of diligence." It involves discarding all ignorance related to happiness and sorrow and acquiring special knowledge, or Vijnana. The core practices are to "always listen to good scriptures" and "follow the Sadguru's word with faith." This requires a state of constant alertness, with one's focus kept firmly on the Self, moving beyond the dualistic thinking of "me and you." A significant aspect of this path, as highlighted in Chapter 17, is its effect on others. When people observe the righteous conduct of a person dedicated to this path, they are inspired and find the way to their own salvation, leading to the easy salvation of countless other souls.
