Although the altar of havan should be prepared in consultation with the priest, but nowadays the altar of havan is also ready. Many priests even dig a pit in the ground and build an altar with sticks. According to the scriptures, five rites of altar are performed. Scrape the altar or copper tank from south to north in three kushas. Then throw the altar or copper tank in the northerly direction from those kushas. Cleanse the earth by dung and water. From Kushmool, make three lines of ten long fingers starting from the south and start towards the north. Take out the soil on the lines with the South ring finger and thumb, keep it three times in the left hand and then keep all the soil in the right hand. Then throw the soil towards the north. After this, water the water tank. In this way, perform the five sacraments of the land and keep the holy fire on its south side.

After lighting the fire in Havan Kund, the sacrifice of fruits, honey, ghee, wood, etc. is important in the holy fire. Deer and laughter are considered auspicious in relation to which fingers should be used while performing Havan.

Laughter posture is that in which the shortest finger is left without the use of kanistaka with the help of the remaining three fingers and the thumb.
Smell, incense, lamps, flowers and naivedya are also offered to Agni Dev. Ghee is then done with mixed incense burner or just with ghee. The scriptures describe giving three ahuti to intensify fire from ghetto. Speak the following mantras with ahuti.
