Guruji, Gayatri mantra is to be chanted mentally whereas other mantras like ‘Om Namah Shivaya’ should be chanted aloud. What is the science behind chanting aloud or doing it mentally?
Sri Sri Ravi Shankar: You know when you sing aloud, it creates more energy all around, so singing has its own type of energy; mentally chanting it has its own energy. But main thing is the ‘bhaava’, the feeling behind it.
