This havan can be used in homes, temples, religious ceremonies. Since mantras are revealed by Enlightened sages, all mantras carry immense power within them. Once energized, till the end of the homa, the fire itself becomes a deity
Havan Kund is one of the most important part for the ritual. Havan Kund is the center place in a Havan in which the fire is put and all the oblations/offerings are made. It could be considered like a sanctum sanctorum for a Yajna. The structure of the havan kund itself generates energy to perform the rituals. Made as per authentic vedic science in copper
Then several oblations (ahutis) are offered into the fire using Havan Samagri, at the end of every mantra. The smoke that emanates from the fire receptacle - homa kunda - energizes the whole space where the homa is done and creates a positive effect in that place. Copper is well known for its grasping capacity
Copper can destroy bad spirits like Raj & Tam (i.e. darkness & bad behavior). The spiritual vibrations are attracted towards copper items easily. Just as copper has the ability to absorb the sattvik frequencies of deities, it has also capacity of transmitting them. Thus it becomes rich in divinity in a short period
Havan Kund is a sanctified element used in ritual procedures from where the enlightened fire acts as a medium for exchanging our prayers to different deities
