Homa are thus acts of invoking benefits for all using good smoke, beneficial particles and propitious chants from the Veda.
Hotr, from this Hu, Homa, is one who knows the way, technique of worshipping or invoking for attaining benefit. It is from this we get words such as Agnihotri who worships, invokes fire for benefits.
The smoke emanating from a Homa, though seen by many today as a pollutant, actually was our ancients’ counter to various kinds of pollution.
