Dharma represents the path of righteousness, duty, and moral responsibility. It is often associated with "good." Adharma, on the other hand, signifies unrighteousness, immorality, and "evil." The concept of dharma forms the moral and ethical foundation of Indian mythology.

Indian mythology features various deities and demons (asuras) who embody the struggle between good and evil. Deities like Vishnu, Shiva, and Brahma represent goodness, creation, and preservation, while asuras like Ravana, Hiranyakashipu, and Mahishasura symbolize evil and chaos.

The Ramayana, one of the most famous Indian epics, narrates the story of Lord Rama, an incarnation of Vishnu, and his battle against the demon king Ravana. This epic explores the triumph of good over evil, with Rama upholding dharma and defeating the adharmic Ravana.

The Mahabharata is another epic that delves into the complexities of dharma. It tells the story of the Kurukshetra War, where the Pandavas, who represent dharma, fight against their Kaurava cousins, who are driven by adharma. The Bhagavad Gita, a part of the Mahabharata, features a conversation between Lord Krishna and Prince Arjuna on moral dilemmas and duty.

The concept of karma, the law of cause and effect, is central to Indian mythology. It emphasizes that one's actions, whether good or evil, have consequences. Good deeds lead to positive outcomes, while evil actions result in negative consequences, often in this life or the next.

Lord Krishna, an avatar of Vishnu, is a significant figure in Indian mythology. His life and teachings emphasize the importance of righteousness, love, and compassion. The story of Krishna includes his battle against various demons and his role in upholding dharma.

Many Indian deities and symbols are associated with the struggle between good and evil. For example, the goddess Durga is often depicted slaying the buffalo demon Mahishasura, symbolizing the triumph of good over evil. The image of Lord Shiva with a serpent coiled around his neck represents his control over destructive forces.

In this popular myth, deities and demons collaborated to churn the cosmic ocean to obtain the nectar of immortality. This story highlights the eternal battle between good (deities) and evil (demons) for ultimate power and the importance of cooperation.

The tale of Prahlada in the Bhagavata Purana showcases the idea that devotion to God can protect individuals from evil influences. Prahlada, a devotee of Lord Vishnu, withstood the evil actions of his demon father, Hiranyakashipu.

The belief in reincarnation is prevalent in Indian mythology. It suggests that individuals undergo multiple lifetimes to learn and evolve spiritually. One's actions in past lives influence their current circumstances, emphasizing the consequences of good and evil deeds.
