When rama and sugriva each other in the ramayana what might there alliance reveal about ancient indian culture

In the Ramayana, When Rama and Sugriva help each other in the Ramayana their alliance reveal about the value of friendship in ancient Indian culture.

When near the Pampa lake both Rama and Laxman were in the search of Sita who was lost, this situation flowered the friendship between Rama and Sugriva.

In the Rishyamuka hill, Sugriva was hiding from Vali. Upon seeing Rama and Laxman from a distant place, he finds out their identity by sending Hanuman to identify. Hence, Hanuman was able to effectively enquire about them and assess their situation. Later upon introducing himself, Hanuman agrees that he assumed a form and that he is a monkey in real in direction of his master Sugriva. Hanuman leads them to Sugriva and in the time of fire Rama and Sugriva pledge to remain friends and that Rama assures to eliminate Vali. Such instance leads to lasting friendship and love between both. This depicts the act of selflessness and working for the welfare of others.
