Simply by vibration the atmosphere will be cleansed and purified. Just like when there is thundering sound in the sky, it does not require to understand by any particular language. That very vibration . . . and the origin of creation is sound. The grosser elements are visible, but the creation takes place from finer elements.
The sound is the symptom of the sky. By sound we can understand that there is sky, ether. Then, by sound vibration, there is circulation of air. And you have got practical experience, when there is very loud sound vibration, sometimes there is very strong wind also. So by sound vibration, the wind is started, and by strong wind, electricity is produced. From electricity, water is produced, perspiration. And from water, earth is produced.
So sound is the original element of creation. In Sanskrit language it is called śabda-brahma. Brahman, or the Absolute Truth, is . . . first appears . . . absolute Truth becomes knowable by sound. In the Bhagavad-gītā it is said—the Lord says—raso 'ham apsu kaunteya prabhāsmi śaśi-sūryayoḥ, śabdaḥ khe (BG 7.8). Śabda means sound.
If we want to see God, so let us hear first of all the sound vibration, because that is the beginning. In the Bible also it is said: "The Lord said, 'Let there be creation,' and there was creation." So "Let there be creation," this is sound, transcendental sound. So one who says this word, "Let there be creation," He is not within the creation. Because He, God, is speaking, "Let there be creation" means He is existing before creation.
