Havis in Hindu tradition is the term used to refer to the materials
that are offered during a Homa or Yajna. Havis materials are tossed into specifically
created fire. This offering is accompanied by chanting of mantras. Agni Dev or
Fire God is the one that carries the Havis to the different gods.
The usual offerings include ghee or butter. Coconut is
offered during pujas dedicated to Ganesha.
Havis is offered in simple homas
performed in home. It is also offered during all important Vedic yajnas.
The sacrificial offerings are meant to please the gods and
goddesses.
