The following is a prayer from “The Great Perfection Buddha in the Palm of the Hand: The Lama’s Oral Instructions Upon the Recitation and Visualization of the Preliminary Practice of Ngondro” as revealed by Vidydhara Terton Migyur Dorje
The syllable GURU is the Guru in the hell realms, Guru Nampar-nön.
Reddish-black in color, he holds a vajra and a scorpion,
Protecting all beings in hell from the suffering of heat and cold.
The syllable PED is the Guru in the hungry spirit realm, Guru Nam-nang-ched.
Maroon in color, he holds a vajra and an iron phurba,
Protecting all hungry spirits from the suffering of hunger and thirst.
The syllable MA is the Guru in the animal realm, Guru Seng-ha-ten,
Blue-black in color, he holds a damaru and bell,
Protecting all animals from the suffering of inferior persecution,
The syllable SID is the Guru in the human realm, Guru Pema Jung.
White and red in color, he holds a skull and a vajra,
Protecting all humans from the suffering of birth, old age, sickness and death.
The syllable DHI is the Guru in the jealous gods realm, Guru Nam-par-gyal.
The color of smoke, he holds a Khatvanga and skull,
Protecting all jealous gods from the suffering of competitive warfare.
The syllable HUNG is the Guru in the god realm, Guru Sid-thub-dzin.
Yellow-white in color, he holds a vajra and bell,
Protecting all gods from the suffering of falling to the lower realms.
These six Gurus protect beings from the suffering of the six realms.
