dharani
The term dharani is from a Sanskrit root word that means “to hold or maintain.” Dharanis contain the essence of a teaching and are often compared to mantras, however, they are longer than mantras and are more likely to have intelligible phrases, like sutras. They are said to have the power to heal and protect from harm. Zungdu (Wyl: gzungs bsdus), a collection of dharanis found in the Kangyur, is often recommended by Lama Zopa Rinpoche.
