Whilst I am not a religious person I do like to learn about different religions and I find most of them have very sweet romantic stories. The story I'm going to tell you is from Hinduism and is about their greatest lovers Radha and Krishna.
Krishna was a great Lord with many wives and Radha was a poor Gopi (cattle-herder) whilst they loved each other with the entirety of their souls they were never married. Krishna however never hid the fact that he loved Radha and favoured her above all others. This love that Krishna showed to Radha made his other wives jealous and they became eager to hurt Radha in any way that they could.
One day the wives of Krishna, in their jealousy, decided to burn Radha. They heated a bowl of milk until it was scalding hot and gave it to Radha telling her that Krishna had sent it for her as a gift. Radha drank the bowl of milk and to the confusion of the wives she showed no sign of pain or injury. Confused the wives returned to Krishna.
When they found Lord Krishna he was in great amounts of pain, his mouth full of ulcers from burns. he told the wives that his love for Radha was so strong, and their connection so deep that he would never let any pain come upon her. He would take for himself any pain given to her because that is the true nature of love.
And who would disagree? Those who have loved or do love will know that they would always put themselves in the path of hurt to prevent their loved one suffering and every one of us have seen it.
