Both Ramayana and Mahabharata were on my school curriculum, hehe... Abridged versions, of course, but still. Kamasutra was a gift of my cheeky friends for my 18th birthday, I was also surprised how much of it was about the philosophy of love and relationships, contrary to the common perception of it being a wild sex manual, haha. It was so popular among my friends that I actually only kept the book for a week or two; everyone started borrowing it afterwards, and I'm sure that after 13 years it's still being shared in the circles of friends of friends
Thanks for your recommendations, I'll google them and then order a few right away!
UPDATE: decided on the Ibis Trilogy, found all three books for $33 on the Book Depository! Cheers again
