Types of Havan Kunds their uses and Benefits

Havan or Homa is an age old sacred Fire ritual in Hinduism which has been performed since Vedic era in order to invoke the powerful energies of the Divine. This ritual is also performed to seek blessings of Gods and Goddesses by igniting the Holy Fire. In this sacred ritual, special offering are kindled in the Holy Fire while chanting the Sanskrit mantras. The ritual of Havan is conducted as per the Holy Vedic scriptures. The sacred Fire and the mantras fill the ambience with purifying and auspicious positive vibrations and thus benefit everyone who is attending the Homa in a splendid manner. It purifies the body, mind and soul, elevates spiritually, makes the mind calm and offers a sense of tranquillity.
Why Havan Kund:
The rich Hindu rituals entail invoking the celestial presence of the Divine in the idols of the deities or in the Kalash (vase). But in this Kalyuga, due to pollution, the air, water and earth are all polluted and there are rare chances of them being pure. Hence, if there are impurities when the Kalash or the deity idols are being made, then invoking the divine presence in these idols or the Kalash would not be possible. Therefore, we put to use 'Agni' (Fire), as fire is the one of the two elements that cannot be polluted, the other being Akash (space). We cannot conduct traditional rituals in space hence; we carry out the spiritual sadhana through Fire. Also in Sanskrit fire is known as "Pāvaka", meaning "one who purifies". Thus, the Fire element is one of the purest elements that purify everything that comes into contact with it.
Havan Kund Usage
Havan Kund is basically a reservoir in which the sacred offerings are kindled. The Havan Kunds are energy centres where divinity is evoked. Various Havan Samagri which include wood, herbs and more are burnt inside the Havan Kund along with offering of ghee and Japa of various mantra to invoke positivity and various energies. The shape of the Havan Kund is said to generate a special energy field and also store this divine energy. The energies generated due to the Havan have properties which are bacteriostatic. The peculiar shape of the Havan Kund helps to generates, stores and spreads the divine energies in the surrounding atmosphere, thus filling the atmosphere with divinity.
