Interesting topic, Lola!
As for the lesson I take out of this event, it is that we must always be patient with people who are proving to be an obstacle for us and win them over with peaceful methods. When they continue to be obstinate and our goal is for the betterment of mankind, then we must forcefully move ahead. Even if our goal is not for the betterment of mankind but simply for our betterment, as long as we are not harming others in achieving our goal, we must remove the obstacle in our path, first by being patient and if that fails, then by taking action.
Here's a small example. It's kind of silly in comparison to the Ram Setu story, but let's say that we are preparing for a very important paper for one of our classes in our university. Our TA (teacher's assistant) is grading us unfairly and writing snide remarks on the paper as she grades it, like "you write at the level of a 5th grade student" and "how stupid could you be that you do not know how to adhere to APA guidelines" and "I am surprised that the college even admitted you to our student body. You clearly need to return to high school."
Btw, I am not making this incident up, as this happened to one of my friends last semester. She really suffered because of this TA!
Anyway, you have two options. You could either threaten to talk to the faculty about her or you can try to reason with her. The smart thing to do is to reason with her yourself and explain that she's really hurting you by writing such remarks, and that you'd appreciate kinder criticism instead that would actually help you. This is what my friend did, especially after failing three papers in a row without constructive feedback). She went to the TA's office and had a long talk with her, but the TA rolled her eyes and told her that this was life and what could she do about it? She'd meet with this kind of attitude in her workplace too but she'd have no one to go complaining then.
After trying to reason with her thrice, and finally becoming fed-up as the semester came to an end and her grades did not improve, my friend went to our professor and lodged a complaint against the TA. The professor was dubious about her complaints at first but then took them seriously when three others complained about the same TA. All the students who had complained showed her their papers which had snide remarks written all over them in place of constructive feedback, and the TA was fired.
Anyway, this story I guess is kind of like the Ram Setu...the first attempt having failed but the second succeeding.
However, you never know if peaceful methods will work unless you try them first. The moral of the Ram Setu story is that you should always try to reason with people who are an obstacle in your path, but if they still prove to be an obstacle, then you should take matters into your own hands.
Basically, respect must be given to every being until they lose it, but just because there's a chance that they may lose it does not mean you shouldn't give the respect in the first place.
