The efficiency of the Japa is emphasized according to the degree of concentration. The mind should be fixed on the source. Then only one will realize the maximum benefits of a Mantra. Every Mantra has got tremendous force. A Mantra is a mass fleas or radiant energy. It transforms the mental substance by producing a particular thought movement. The rhythmical vibrations produced by repeating the Mantra, regulate the unsteady vibrations of the five sheaths. It checks the natural tendencies of objective thoughts of the mind. It helps the spiritual power and reinforces it.

Mantras are Sanskrit invocations of the Supreme Being. When the mantras are reinforced and propelled by japa meditation, they pass from the verbal level through the mental and telepathic states and also on to pure thought energy. Sanskrit is the most closely approaches telepathic language of all the other languages. This is because of its affinity to the fifty primeval sounds. It is the most direct way to approach the transcendental state. Mantras cannot be concocted or customized for the individual, despite some current claims. They have always existed in a latent state as sound energies. Mantras have also been codified in the scriptures and handed down from guru to disciple.. Guru, deity and mantra once chosen, should be never changed.
