OM SAI RAM
Respected Sathyakala sister,
Sai Satcharitra is such a book that it is best if you could read one chapter every day.In whatever way you decide to read the book, pleas take the time to read it at a pace where you can spend time at understanding each word and rejoice in the supreme ..our Guru Sai Nath.
I am not a person who knows which days to read which chapters you read it, rather I feel the more number of times you read it the greater peace you experience.Sai bless you in your parayan for their are others who have the correct 'modality you should do the parayan'. The most blessed thing that can happen is if you start to male the life of Baba's and his teachings an integral part of your own very person. Sorry if I have not been of much help.Please understand the concept of Sai our Sadguru is above all.May Sai bless you with ever lasting faith and devotion.
