Lajahoma refers to a specific ritual performed during the Hindu marriage ceremony (Vivaha Samskara). It involves offering puffed rice (laja) into the sacred fire. This ritual is a significant part of the wedding proceedings.
Lajahoma is integral to the marriage ceremony, distinguishing it from other Vedic sacrifices or duties like the Vajapeya sacrifice or the Sannyasin's duties. It is not typically associated with the Panchamahayajna, which are daily obligatory rites for householders.
Based on its traditional role and performance, Lajahoma is exclusively associated with the rituals of a Hindu marriage ceremony.
