In the Sundara Kandam in Srimad Valmiki Ramayana, Hanuman narrates the Ramayana from the beginning up to that point of time, to Sita Devi who is held captive by Ravana. Following this, Thrijada describes a dream where she says that she witnesses Sri Rama Pattabhishekam. Therefore, effectively, the entire Ramayana is covered in this one Kandam and that is the reason Thy doing parayana of the Sundara Kandam alone is considered equivalent to reading the whole text.
In Ramayana, at the time of meeting Lord Sri Rama, Sugreeva has lost everything- kingdom, wife, honour. but later he regains them all. Ravana, on the other hand, has everything in the beginning. but in the end, he loses everything one by one and is finally destroyed too. The reason is simple. Though he was down in the doldrums, Sugreeva held on to the company of the true Sadhu named Hanuman, whereas though he had it all, Ravana set Hanuman's tail on fire thus earning the wrath of God. such is the greatness of Sadhus and their divine company.
One need not accept Lord Rama as God. But if we take a close look at Ramayana, the ideal king and father is portrayed by Dasaratha, the ideal siblings by Lakshmana, Bharata and Shatrugna, the ideal wife by Sitadevi, the ideal dasa by Hanuman, the ideal friend by Guha and even, the ideal enemy by Ravana. Can anyone deny the glaring fact that Ramayana portrays an ideal society?
To the eyes of some even if Ramayana is a myth, the fact that somebody imagined a flying object called "Pushpak vimana" in Ramayana thousands of years ago, is undeniably baffling
Soorpanaka wanted Sri Rama alone. she was destroyed. RAvana wanted Sitadevi alone and he too met his end. Hanumanji wished to have darshan of Sita-Rama and therefore He remains as a chiranjeevi to this day. through this, Ramayana indicates this very deep truth that one should always worship the Lord along with his divine consort (as "Yugalam" )
