"So the LORD scattered them abroad from thence upon the face of all the earth: and they left off to build the city. Therefore is the name of it called Babel; because the LORD did there confound the language of all the earth: and from thence did the LORD scatter them abroad upon the face of all the earth." – Genesis 11:6-9
The ancient language of Sanskrit is the most ancient language known on Earth. It is also the only scientific and metaphysically devised language on Earth. It was the first language to be spoken on Earth, and it will be the last language spoken on Earth.
Sanskrit is directly derived from what one may call the fifty primeval sounds. More in particular, these fifty sounds are derived from the "pedals" surrounding the Chakras, floodgates or energy votices, contained within the suble body of man. Each of the pedals of the different Chakras are connected to what the Yogis call the "nadis" or subtle nerves contained within the subtle or etheric structure.
All things in manifestation have a certain vibration and everything in manifestation makes a sound, either sonically or supersonically. The Ancient Masters, in Their Meditations, heard the sounds made by the fifty pedals of the different Chakras and these sounds became the alphabet of the Sanskrit language.
One of the most potent ways of using Sanskrit is through the ancient Science of Mantra. Mantra in Sanskrit, when diligently repeated, causes the Chakras to vibrate in a different way and enhances their function. It is through the higher Chakras that higher mind is drawn into the aspirant and from there it is translated by the brain as inspiration, higher knowledge and truth. Mantra Yoga, then, as such, is a very valuable practice.
