The main character is Lord Vishnu of course. His consorts like Lakshmi also play important roles. And then there are the various demons that he has to defeat in his different avatars, such as Ravana in the Ram avatar story.
The Vishnu Puran is a vast and complex Hindu scripture. In short, it mainly revolves around the various incarnations of Lord Vishnu. For example, his incarnation as Rama and Krishna are well - known. It also details the creation of the universe, the concept of dharma, and the role of Vishnu in maintaining the cosmic order.
One main event is the story of Vishnu's avatar, Rama. Rama's exile, Sita's abduction by Ravana, and Rama's victory over Ravana to rescue Sita are important. Another is Krishna's life events. His birth, his interactions with the Pandavas and Kauravas, and his role as a charioteer in the Kurukshetra war are key.
The Vishnu Puran is filled with numerous tales. It begins with the description of the creation of the universe. Vishnu is seen as the preserver. His avatars like Matsya (the fish), Kurma (the tortoise) also play significant roles in different events of creation and preservation. The story of Krishna is detailed, from his childhood pranks in Gokul to his role in the great war of Kurukshetra. All these stories are intertwined to show the grandeur of Vishnu and his influence on the world.
The Garun Puran is a religious text in Hinduism. It mainly contains stories and teachings related to Garuda, the divine bird. However, a full in - depth story would involve many aspects such as Garuda's birth, his adventures, his relationship with Lord Vishnu. Garuda is often depicted as a large and powerful bird, and in the Puran, his deeds are recounted which also include his role in the cosmic order and his significance in Hindu mythology.
