There are three types of mantras. One is Sabhri which empowers one with siddhi or mystic powers. 

The second is Tantra which gives ckamatkari (amazing demonstrative powers) at the mystic level.

 The third is Vedic mantra which goes towards achieving eternal peace for the soul. Initiation with mantra from the guru covers most aspects of sadhana (spiritual cultivation). This mantra once given by a guru can erase fear within and diminish demonic influences, if any. Whosoever cultivates the Guru mantra is able to travel to Puramdham, the land of the Supreme Soul.
