There are two basic energy systems in the physical world: Heat and Sound. In performing Yagya, these two energies, namely, the heat from Yagya’s fire and the sound of the Gayatri and other Mantras, are combined to achieve the desired physical, psychological and spiritual benefits.

The fumigation of specific substances in the Yagya - fire is a scientific method of subtulisation of matter into energy and expanding its potential and positive effects in the surrounding atmosphere. The electromagnetic waves generated thereby help in transmitting, at cosmic level, the desired sonic signals ‘stored’ in the Mantras, which are chanted during the process of sacrificing the special materials in the fire.
