One (for instance, the wife's father) who wishes that the hearts of both (husband and wife) may be in accord should observe chastity through at least three nights and should prepare a Sthâlîpâka. Then (the ceremonies) from the putting (of wood) on (the fire) down to the Âgyabhâga oblations (are performed), and while the wife takes hold of him, he sacrifices of the Sthâlîpâka the oblations (indicated by the) next (Mantras; M. I, 14, 1-7); then he enters upon the performance of the Gaya and following oblations, and performs (the rites) down to the sprinkling (of water) round (the fire).
