The most important thing in a Havan is the Havan Kund. It is the
center point in any Havan or Yagya wherein the fire is lit and the
offerings are made. It is either made of bricks or is a copper/stone
vessel. The Kund more often than not is a perfect square.
Steps
The kund is also decorated using paint, flowers, leaves and grains.
The samagri for Havan includes wood (especially mango tree wood and
sandalwood). The wood type used should be such that it burns easily
without creating bad and disturbing smoke. The pieces should be dry and
cut into sizes that perfectly fit the kund.
A pre-defined combination of thirty six herbs as well as other
ingredients like ghee, incense sticks, lamps, camphor, kumkum etc.
A Havan can be performed either indoors or outdoors. All devotees
sit around the Havan Kund.
The ones participating in the Havan have to be the primary ones to
circumvent it.
Specific mantras are chanted and the devotees pour in the samagri
with their right hand using the two middle fingers and the thumb to hold
it.
The pandit or the main devotee holds a long wooden spoon to pour in
the ghee, one spoon at a time.
While making the offerings, the pandits chant the mantra and each
time the mantra ends with a Swaha. The swaha is like a cue for the
devotees to pour in the offerings.
