What is trikaya?

Trikaya, a concept in Mahayana Buddhism, refers to the "Three Bodies" of a Buddha. These are the Dharmakaya, which embodies the ultimate truth and reality; the Sambhogakaya, the body of bliss that enjoys spiritual experience; and the Nirmanakaya, the physical embodiment that appears in the world to teach and guide sentient beings. Together, these aspects illustrate the different ways a Buddha can manifest and interact with the universe. The concept emphasizes the complexity of enlightenment and the various forms it can take.
