Ramayana is an Epic which everyone should read. It discusses in great depth about character , values and sacrifices. It focuses on how Lord Rama despite facing problems was able to conquer them and how he brings back the balance of good and evil by defeating Demon King Ravana and bringing his beloved wife Mata Sita.
The basic teaching fo Ramayana is that no matter how powerful evil is, it will always be defeated by Good. Truth always wins, no matter how vicious or poisonous lie is because even a bitter truth oozes with positivity and the sweetest lie has the darkest agenda behind it. The win of good over evil is a universal fate.
