The friendship between Lord Rama and Lord Hanuman shows us that we should be loyal and supportive in a friendship.
A relationship is based on the foundation of trust. Goddess Sita did a Trial by fire to gain Lord Rama’s Trust.
Lord Rama and Lord Lakshmana had a very good brotherly relationship as the family relationships are based on Loyalty, Selfless love etc.
A marriage like Lord Rama and Goddess Sita only works when the couple commits to each other and share their responsibilities.
The love and peace between parents and children should always be sacred like King Dashrath and Lord Rama.
Ignoring family can create tension and misunderstandings between each other and also can ruin relations just like Ravana and Vibhishana.
Relationships not only require loyalty, it also requires decisions where we have to make sacrifices for each other just as Bharata did for Lord Rama.
