Joseph Abraham writes in Malayalam on the spiritual philosophy of Osho (Bhagwan Rajneesh), focusing on the theme of shunyata — emptiness or inner void — as a path to awareness and liberation. Shoonyathayude Pusthakam (The Book of Emptiness) makes Osho's teachings on silence and non-being accessible to Malayalam readers, and is published by Silence (The Osho Bookshop), Kerala.
