How many 'Saptahs' or weekly recitations of a Sadguru's biography does the preface say are necessary to attain salvation?

The Preface (Chapter 0) does not specify a required number of weekly recitations, or 'Saptahs,' for achieving salvation. It mentions that the best service is to write a Sadguru's biography and to 'perform hundreds of readings (Parayans) and weekly recitations (Saptahs).' However, as described in Chapter 0, the emphasis is not on the quantity but on the quality and disposition of the devotee. The text highlights that this service should be done with 'a firm resolve, pure heart, excellent faith, selfless love, and unwavering devotion.' The path to salvation is presented through the manner of devotion, not a numerical target.
