Thanks for your reply Angelz! I'm glad that your Guruji appreciated my questions! All my doubts are cleared up now!
Even Ramanand Sagarji said in his show that Tulsidasji did not write Uttar Kand, because he could not bear to write about Sita Ma's sufferings, but he (Dada Sagar) also said that at the behest of others, Tulsidasji wrote Uttar Kand very later on. Is that true? If not, then I think it is wrong to show Luv Kush fighting their uncles (as written in other books and shown in about every movie or serial) because it is written no where in Valmiki that they did.
But I'm surprised that about every movie/serial based on Uttar Kand show Luv Kush fighting their uncles and tying up Hanuman. Not one (as much as I know at least) follow Valmikiji's Uttar Kand. Isn't Adhyatma Ramayana another famous Ramayan? I think in it's UK, Luv Kush fight their uncles. Don't know...
Yes, I too agree that movies or serials should never be taken as sources for our scriptures, but they're fun to watch and sometimes, people's interest in scriptures arise from serials, and when the serial is over, they want to find out the true story so do their own research based on books.
Ramanand Sagarji's Ramayan was taken well, very close to Ramcharitmanas, but his Uttar Kand, though also taken well, did not stick very much to the story. Though his Shri Krishna serial also has some mistakes, it is still fun to watch because the way he showed Radha and Krishna's relationship was so beautiful.😍
