The difference between an Enlightened Dharma Protector and a worldly Dharma Protector is that the former is a Buddha whereas the latter is not. Many of the Dharma Protectors who are most commonly relied upon are Enlightened Beings, such as Dorje Shugden, who is an emanation of the Buddha Manjushri.

Enlightened Dharma Protectors’ principal function is to protect our Dharma practice, not to help our mundane affairs. Famous Enlightened Dharma Protectors are Palden Lhamo (an emanation of Tara), Six-Armed Mahakala (Avalokiteshvara), Four-Armed Mahakala, Kalarupa and Dorje Shugden (Manjushri), and Setrab Chen (Amitabha). The most famous of the unenlightened Dharma Protectors is Nechung / Pehar. These unenlightened Protectors are usually worldly beings who were oath-bound by Lamas to stop causing harm and to serve and protect the Dharma instead.
