Need to verify if the author is a person or an organization. Sometimes, non-profits or educational groups produce such PDFs. If it's a well-known work, cite reviews or summaries. If not, acknowledge the limited information and focus on plausible interpretations. Since the title includes PDF, it's digital, so discuss accessibility and usage in the digital age, especially in Kerala where Malayalam content is prevalent.
