Sometimes transliterated as: Samarohana, SamArohaNa, Samaarohana
Samārohaṇa literally means ‘making the fire ascend’.
If an āhitāgni, one who had ceremonially established a Vedic fire, wanted to go on a pilgrimage, he could put out the fire by the site of samārohaṇa and re-establish it after returning.
In samārohaṇa, the āhitāgni had to warm his hands on the gārhapatya fire with appropriate mantras causing Agni to enter into his body. Alternatively, it could be done by warming the araṇis and another piece of wood which will be the subtle dwelling place for it till he returns. When the same process is carried out to establish the fire which is once established elsewhere, it is called samāropaṇa.
