Mantra is a Sanskrit word consisting of the root man "manas or mind" and the suffix tra meaning, tool, hence a literal translation would be "mind tool". Mantras interpreted to be effective as sound (vibration), to the effect that great emphasis is put on correct pronunciation (resulting in an early development of a science phonetics in India). They are intended to deliver the mind from illusion and material inclinations. Chanting is the process of repeating a mantra. Sai is the name of God given to Sai Baba of Shirdi. In Sai Baba's saying one can note that Sai Baba said that even the chanting of name Sai with Shradha (Faith) will burn away the sins (the sanskaric effect one reaps of hurting other beings) of speech and deeds. Sai Baba used to ask devotees to do Naam Saptah. Any divine name of God or mantra would be chanted continuously for a week. By this Sai Baba also indicated that the effect of chants gather more spiritual energy when it is being done on continuous basis.
