In Mahayana teachings, Nirvana is characterized as “pure” because it is free of the defilements of greed, hatred, delusion, pride, and self-doubt; as “blissful” because it is free of suffering; as “eternal” because it is free of impermanence; and as the “true self” because it is free of the false idea of a self. Essentially, the seal of Nirvana is the seal of nonclinging and freedom from all attachments, limitations, and false, self-serving views. It is not a thing that we can create through our own efforts, receive from others, or have in the way we might possess an object or have an experience. It is the true nature of reality which we awaken to through taking faith in the Buddha’s teachings and upholding them in our lives.
