Often we tend to consider Sanskrit as just another language, like English, Hindi, Arabic, Urdu etc. Sanskrit in fact is not a language; it is the science of dhwani coded in the form of mantras, shlokas and uchharans that were revealed to the vedic rishis in heightened states of dhyan. It is the vani of devas.
In the English language the alphabets from A to Z are not arranged in any logical or rational manner. There is no reason why F is followed by G or why P is followed by Q etc. On the other hand, Panini in his first fourteen Sutras arranged alphabets in the Sanskrit language in a very scientific and logical manner, after close observation of the sounds in human speech. For example, the vowels, a, aa, i, ee, u, oo, ae, ai, o, ou are arranged according to the shape of the mouth when these sounds are emitted, a and aa, are pronounced from the throat, i and ee from the palate, o and oo from the lips, etc. In the same way the consonants have been arranged in a sequence on a scientific pattern. The (ka) varga (i.e. ka, kha, ga, gha, nga) are emitted from the throat, the (cha) varga from the palate, the (ta) varga from the roof of the mouth, the (ta) varga from the teeth, and the (pa) varga from the lips. No language in the world has its alphabets arranged in such a rational and systematic manner.
