Buddha Nature is a fundamental concept in Mahayana Buddhism that suggests all beings possess an inherent potential for enlightenment. It implies that everyone has the capacity to realize their true nature, which is pure and free from suffering. This potential is often obscured by ignorance and negative emotions, but it can be uncovered through spiritual practice. The idea of Buddha Nature emphasizes that enlightenment is not exclusive to historical figures like Siddhartha Gautama (the Buddha) but is accessible to all. By recognizing and nurturing this innate quality, individuals can transform their lives and attain a state of wisdom and compassion.
