What are the scriptural rules for householders regarding food, as explained in the context of Sai Baba's life?

Chapter 9 details the strict scriptural injunctions for householders concerning food. It is stated that the master of a household should first offer a portion of any food cooked in their home to ascetics and celibates. The text emphasizes that if a householder consumes the food themselves without first making this offering, they begin to incur the need for penance. This is because cooking is prohibited for ascetics, and the scriptures have entrusted their sustenance to the householders, making it their duty to provide for them.
