When someone abuses you verbally, how do you feel?
If someone says that you are a donkey, how do you feel? What does it do to you? What does it create? Anger! It shakes you. It creates some negative vibrations; you feel angry. You feel some sensations in the stomach, in the head. If a bad word can create so much physiological reactions in you, do you think a very sweet name, a chant, which includes a lot of energy of the cosmos does not do anything to your body?
It is unscientific and stupid to think that a mantra does not do anything to your body. That is not the case! It does.
. That is why it is called mantra kavach(armor); a mantra creates the sense of an armor around your body.
Sometimes you meet some people and you feel like talking to them. You get good vibes from them. Sometimes you meet people and you want to avoid them. Do you know why? The negative vibes around a person make them repulsive. Mantras turn around these negative, repulsive vibrations, into more positive and attractive vibrations. This is the advantage of mantra chanting.
Today, if you go to New York, you will find hundreds of places where they learn chanting. People go for one hour in the evenings to chanting classes. They chant ‘Om Namah Shivaya’,’ Om Namo Narayana’, ‘Sri Rama Jai Ram Jai Jai Ram’. Of course, they have a different pronunciation.
In China, they say, ‘Ladhe Ladhe’ instead of ‘Radhe Radhe’.
In Taiwan, 7,000 people to 8,000 people sing ‘Ladhe Govind’ instead of ‘Radhe Govind’.
People have seen that there is an effect. And there really is!
Now when should you do it? If you do chanting after pranayama and meditation, then it has a better result. If you do it at a superficial level, then it is not so effective.
