The Buddha’s eternal life should not be seen as a violation of the three marks of impermanence, suffering, and selflessness, which apply to all other forms of life. This is because the Buddha’s eternal life does not depend upon a body or mind characterized by the Three Marks. Rather, the Buddha’s eternal life is the true Nirvana of Buddhahood, which is characterized by purity, bliss, eternity, and true self as opposed to the impurity, suffering, impermanence, and false self that characterize the life of delusion.
