Definition - What does Shabar Mantra mean?
A shabar mantra is one created in local village dialects and languages rather than the traditional language of yoga, Sanskrit. Unlike many of its Sanskrit cousins, the shabar mantra is not chanted for energy of its sound vibrations, but for its meaning in the local language. Sanskrit mantras most often have no direct translation, although they may be prescribed meaning.
The term, shabar mantra, is often associated with a set of such mantras that is believed to have originated with or been disseminated through Guru Gorakhnath in the 11th or 12th century. These particular shabar mantras are said to have potent healing or generally powerful properties.
Yogapedia explains Shabar Mantra
According to Hindu mythology, Lord Shiva created shabar mantras for himself. He revealed one of his most powerful to Parvati, the mother goddess. This shabar mantra would allow people to have whatever they wanted or wished to achieve simply by chanting it. It is said that Gorakhnath later revealed this mantra to the people for their benefit.
These mantras do not follow any particular style or code. As colloquial, shabar mantras may be direct, demanding and, at times, crude. They fall into a number of categories based on their intended purpose, which is not always altruistic: strengthening, gravitating, creating peace, restricting an adversary, killing, creating a rift, and separating.
