Forth from his navel came mid-air; the sky was fashioned
from his head;
Earth from his feet, and from his ear the Quarters. Thus
they formed the worlds.
From his navel was the atmosphere; from his head the sky came into being (''sam-vṛt''); from his (two) feet the earth, the quarters from his ear (''çrótra''): so shaped they the worlds.

The surface that matched
Each passage folds to its own comparison surface. Accents, word breaks and sandhi are removed before comparison.

These links are derived by comparing normalised Sanskrit surfaces. They show that two collections carry the same wording. They are not, by themselves, a demonstrated line of transmission between them, and the direction stored on an edge is a property of how it was built.
Yajurveda is one of four collections held here. Cross-corpus comparison bottoms out at the weakest shared surface, because a Devanagari text and a romanised text share no code points.
How these were derived1
Parallelism is symmetric and this graph stores it as a directed edge, so these relations are traversed in both directions and each row states which way the stored edge ran. All 1,684 REUSES_TEXT_FROM edges point Samaveda-to-Rigveda, and 1,421 Rigvedic passages have reuse edges only inbound; following the arrow would show those 1,421 verses no reuse at all.
