What is the significance of a 'seven-day reading' or Parayana as mentioned in the Satcharitra, and what are its intended effects?

The concept of a seven-day reading, or Parayana, is highlighted as a potent spiritual practice. As detailed in Chapter 18, a devotee named Sathe was instructed by Sai Baba to undertake this practice. Baba affirmed its value by ordering another repetition and explaining that "By reading this book of the Guru, devotees become pure." He further stated that by performing the Parayana, welfare will be achieved, God will be pleased, and the bonds of worldly existence will be broken. This shows that the seven-day reading is not just a simple ritual but a profound method for spiritual purification and liberation, endorsed directly by Baba for the welfare of his devotees.
