Can you explain the concept of serving 'God in humanity' (Jan-Janardan) in the context of creating a community around Sai Baba's teachings?

The concept of serving 'God in humanity' is directly linked to the creation and communal study of a Guru's biography. As described in Chapter 0, when a writer creates a detailed poetic Guru biography, they are performing Guru service. Furthermore, when other devotees are able to study and perform Parayans of that same work, the writer gains the additional merit of serving 'God in humanity' (Jan-Janardan) and performing public service. This suggests that facilitating the spiritual growth of the wider community through a shared text like the Shri Sai Satcharita is a profound form of service.
