|Hindus went a
step further. The science of sound. Most mantra sounds do not have any meaning.
If there was a meaning, perhaps it will loose its effects.
There are provisions of how to do mantra jaap and when and
where to do them to obtain a given result.
Mantras can also be used to do Nishkam puja. Then the sound
is used to transgress mind.
The vibrations of the sound goes to every cell of the body.
The mantra is internalized by making it a continuous
phenomenon. Now you do not have to chant Om,Om from outside.
Your whole existence is echoing with the sound. In such a
state mind is bypassed.
It simply is dropped. There is no desire to achieve any
thing. If there is no result or goal in mind the mind is no more needed.
