Yajamāna — the one for whom the rite is done
The yajamāna is the host of the rite — the person or couple who makes the saṅkalpa, provides the materials and receives its blessings. In household rites a husband and wife traditionally sit together as joint yajamānas.
Even when a priest recites everything, the yajamāna is not a spectator. Repeating the words, making the offerings with your own hands and keeping a respectful mind are what make the rite yours.
