The sound vibration creates a concentrated force field of the total powers of the Supreme. To understand this, one needs the realization of the true spiritual knowledge of fourth dimension. Here, prayers, meditation, concentration, yoga and spiritual knowledge to develop an intuition are very helpful. The world, the planets, the stars, the sun and the whole universal space are filled with the electromagnetic force fields. Light and the heat energy from the sun are able to travel in space through these particles of the wide spectrum of electromagnetic waves as vibration or pulse. Individual devotees, by regularly following certain established rules of Niyama and Dharma, performing their karmas, improve their mind power by meditation and then recite the manthras with proper words and sounds, create this force field around themselves and their surroundings.

The Guru or priest, by performing certain Nithya Karma and regular poojas, and following his Dharma regularly creates a force field around himself to make him capable of performing certain services for installed Vigrahas or Moorthis which also has similar force fields of energy. These Gurus and priests have gone through a rigorous training and study of the Vedas, Agamas and philosophy, follow all the Niyamas and get the initiation of Samaya Dheekshai or Acharya abhishekam to qualify for performing the Temple or home prayer rituals. When a large group of devotees recite the mantras properly pronouncing the sound, with repeated recitation and also meditation, it creates a force field of vibration and causes the effect of the thoughts becoming reality. When a large group of priests recite the Veda Mantras the power of the force fields created in the area is enormous.

It has been noted in computer sound recordings programs, that the music sound gets converted to wave-table figures and the waves formed angles and figures of graphic images on computer screen. Similarly when the complete texts of Sri Lalitha Sahasranaamaa are repeatedly recited properly, it forms images resembling a Sri Chakra. It is possible that similar powers exist with other Manthras and Yanthras. These suggest that the sages probably saw the recitation of sounds in various Veda mantras caused a vibration of the electromagnetic particles creating the various Chakras as force fields.

Now, if you happen to see holographic picture you will understand that in this image every bit will represent a whole three dimensional image of the total object. Now, if we control the electromagnetic sound waves like a laser beam to run through a force field, formed like Sri Chakra or other Chakra, may be there is a large holographic image of the Deity form of manifestation of the Divine power being worshipped. The image so created may have any of the several forms, male or female, with four hands or more, even eighteen hands of Durga, human face or animal face as in Sri Ganesha. It all depends on the power of the Manthra and Chakra.
