Messages from stava

"stava" is a term that has various meanings depending on the context. Based on the SMS messages, it seems like "stava" could be related to spirituality or religious hymns as one of the messages mentions stotra and stuti which are types of devotional poetry in Hinduism. However, this cannot be confirmed without further information. On the other hand, based on web search results for "stava", there seem to be multiple definitions such as staff (in Swedish), spell/writing individual letters correctly (also in Swedish) and even a village name in Northern Italy where an unfortunate dam collapse occurred back in 1985. Therefore, it's difficult to determine what kind of service/app/website/product/campaign/company "stava" refers to solely from these sources. It may require additional research or more specific details about how exactly you received those SMS messages mentioning "stava".
