The concept of the 'Three Bodies of Buddha' in Mahayana Buddhism describes three aspects of a Buddha's existence: the Dharma Body (Dharmakaya), representing truth, the Enjoyment Body (Sambhogakaya), which allows a Buddha to interact with other enlightened beings, and the Emanation Body (Nirmanakaya), the physical manifestation that appears in the world to guide beings to enlightenment. Together, these three bodies provide a comprehensive framework for understanding the transcendental, spiritual, and physical presence of Buddhas, explaining their eternal and accessible nature in Buddhist cosmology.
