What are the specific instructions for performing a 'Parayan' or 'Saptah' for worldly prosperity, as mentioned in the text?

The source material from Chapter 0 mentions that Guru biography texts can be used with desire (Kamya) for worldly prosperity, and that one can perform a 'Parayan or Saptah' of these works. However, it does not provide any specific instructions, rituals, or procedures on how to conduct such a Parayan for achieving worldly goals. The text only categorizes the purpose of the recitation as either 'Kamya' or 'Nishkam' but does not detail the methodology for either practice, making it impossible to provide instructions based on this information.
