The power of sound vibrations is long since acknowledged in the field of science. These vibrations can penetrate the energy spheres at the subtle and cosmic levels. All the alphabets of the Sanskrit language are endowed with special vibrational powers, which set out harmonious wave patterns when pronounced.
It is interesting to note that Dr. Howard Steingull, an American Scientist has established that recitation of Gayatri Mantra produces 110,000 sound waves per second. In fact recitation of the Gayatri Mantra during the fire-worship (Yagya) acts supplementary. The patterns of chanting of Mantras are so designed that they latently contain the essence of the music or the quite essential sound of the torrent of life sustaining energies emanating from the cosmic energy center of the corresponding Mantras. (The cosmic energy center a deity associated with the Gayatri Mantra is Sun). Uttering of these Mantras produces vibrations which are soothing to human mind, all plant and animal life. These vibrations also help in spreading specific energy waves in the surrounding atmosphere as the oblations are offered.
