Jaiminīya (Talavakāra) Brāhmaṇa 1.29

1.29

Mounting the Svadhā as a golden boat, he journeys from there toward co-existence with Prajāpati.
He offers for five days.
Twenty oblations are completed.
Twenty-part indeed is Prajāpati.
This indeed is death, which is named Prajāpati the Abundant.
Having pacified him by means of those oblations, he conquers the sky among worlds, Prajāpati among gods.
He ascends to union, to co-existence with the god Prajāpati, who, knowing thus, offers the fire-offering.
