I recently saw a video of a renowned modern-day Guru Sri Sri Ravishankar, where he said inter-religious marriages are fine if the partner is spiritual. I wondered whether this is the teaching of Hindu scriptures or his personal opinion.
What do Dharmasastras say about inter-faith marriage? Does it encourage it? Or does it prohibit it? If it is forbidden, what punishment or prayaschitta is prescribed? I am especially concerned about when a Hindu girl gets married to a non-Hindu man.
Non-Hindus are frequently referred to as the Yavanas. So is marrying a Yavana allowed? Is there any instance in Hindu Purana or Itihasa, where a Hindu girl got married to a Yavana?
