Among ordinary Javanese, traditional animistic practices of spirit worship coexisted easily with a tolerant and accommodating Islam, while merchants often embraced a more orthodox version of the religion in line with Middle Eastern traditions.
In this quote it shows how Islam adapted, similarly to Christianity, differently across groups of people instead of a uniform belief system. This shows how they were able to blend everyday religious practice with other older traditions. Again showing how religion was shaped by local culture or things like social context, as it highlights the flexibility Islam had as it spread similarly to Christianity.
