May I know if mental Japa is more powerful than the practice of chanting of a Mantra loudly?
A. Mental Japa is indeed more powerful. When mental Japa is successfully practised all worldly extraneous thoughts drop off quickly. In Vaikhari and Upamsu Japa, there is scope for the mind to have its own ways. The tongue may be repeating the Mantra but the mind may be busy with other thoughts. Mental Japa closes the avenues, though worldly thoughts may try to enter the mind. In other words, the trap door through which thoughts enter the mental factory is closed when the Mantra is being repeated. The mind is filled with the power of the Mantra. But you should be vigilant and prevent sleep from overpowering the mind. Desires, sleep and various sensual thoughts obstruct the successful performance of mental Japa. Regular practice, sincere attempt, sleepless vigilance and eamestness can bring complete success in mental Japa.
