The document discusses the concept of karma in Hinduism and Buddhism, which holds that all intentional actions, whether positive or negative, have consequences that can affect the current life or future lives through reincarnation. Karma is seen as a moral guide that encourages ethical behavior by creating positive or negative consequences based on one's actions, and as a way to understand and accept life's challenges as resulting from past deeds. The key principles of karma include responsibility, moral development, justice, motivation for self-improvement, interconnectedness, and reflection on personal growth.
