Transit overlay

Graha currently in nakṣatra Maghā (index 9) lands in the Madhya ring, position 6. This is the structural fact; whether the transit indicates beneficence or pressure requires consideration of the graha's natural temperament, other transits, and the chart context — that synthesis belongs to a Jyotiṣī, not to the engine (Truth #5).
