Vāta seat — sacral and pelvic anchor
Apāna field / lower trunk
This point marks the sacral and pelvic end of the Vāta field, especially the downward-moving apāna current. The classical texts support a lower-body Vāta emphasis, but they do not draw a sacrum point on a front-view silhouette; the coordinate is therefore a broad editorial anchor rather than an anatomical claim.

Sources
Caraka Saṃhitā (primary_canonical)
Doṣa-site discussions associate Vāta with the lower trunk and its downward-moving functions; the text does not supply a plotted sacral coordinate.
Aṣṭāṅga Hṛdayam (primary_canonical)
Vāta's lower-body and apāna field ground the pelvic anchor; the front-view point is an editorial projection.
