When missionaris teach their religion, they dont have a universal teachings. Their messages can be understood by people who are already christians (then why people convert ? people nowadays dont ask this question. They know why people convert).
But when hindu saits go abroad, they have a universal message that can be understood by masses. Vedanta, ahimsa, yoga and meditation are just few. That is why hiduism is a hit abroad.
Every story of Hinduism gives a uniersal message. You take or not take is your choice. Hinduism never claims that it is ultimate truth.
Ram is a charater that inspires millions. If you are humble and spiritual, you will get the message from Ramayana. If you are an Atheist or monotheist, you will NEVER get it for obvious reasons.
