You know that, according to the science of acoustics, the origin or the seed of a word remains in latent form in paráshakti [the primordial desire for expression]. The latent or dormant condition of a word is called pará. At the first stage of expression, one visualizes that word with one’s inner eye. Then it takes the name of pashyanti (the feminine gender of pashyat with the suffix shatr). Thereafter, the stage of continuous effort that goes on from the navel to the vocal cord regions to transform the visualized word from mental image into an expressible state or language is called madhyamá. The stage that follows this madhyamá, when it goes on pushing … stirring the uvula continuously, is known as dyotamáná. Afterwards, when, with the help of the uvula, it is transformed into an audible sound, it is called vaekharii. At last, when borne by the uvula, it comes out between the parted lips, it is shrutigocará. This very vaekharii shakti manifests itself through the uvula. When human beings attain proficiency in controlling vaekharii power by dint of spiritual sadhana, it is called vaekharii siddhi. Even without following systematic spiritual practice, through continuous normal practice also one can gain control over this vaekharii shakti, though only to some extent. The power required to issue commands or to give orders is called galavaekharii. With the help of this galavaekharii, human beings can augment the depth of the sound, and according to their sweet will can add a quiver to the voice. Adding sweetness to a quivering voice nonetheless warrants concentration of mind in the kúrma nád́ii [energy channels related to vocal cord] which is close to the centre of vaekharii power. Even if the measure of sweetness in the vaekharii shakti is little, this will not be so in the kúrma nád́ii. Insufficient knowledge notwithstanding, many so called scholars triumph over their rivals in a battle of logic by dint of sheer vaekharii shakti. But the ship of their erudition leaks when they have to cope with real pandits.

[Simply by playing on words and thereby confusing people, a section of so-called learned pandits may derive intellectual pleasure, their intellectual thirst may be quenched, but the human heart remains unsatisfied. These intellectuals, steeped in intellectual vanity, may get temporary satisfaction, but they can never attain salvation.]
