Dr. Vyas explains that later that still deep in thought, Valmiki is encouraged by the God Brahma to speak about this injustice by telling the story of the ideal man Rama and use the poetic style of the curse as the format of Ramayana.  Further, it is said that the Ramayana was taught to Rama’s sons by Valmiki and then to the people. In this light, we could understand the origin of the Ramayana as addressing injustice.  I will address later what I think is the greatest injustice in the story; Rama’s rejection of Sita.
