Dasha begins from the natal framework
A dasha sequence organizes life into planetary periods derived from the birth chart under a chosen system. Different dasha systems use different rules and emphases.
Transit begins from the current sky
A transit view compares current planetary positions with the natal chart or another reference chart. It changes as the planets continue to move.
Interpretation asks where the views overlap
A practitioner may consider whether a natal period and a current transit point toward the same theme. Agreement can strengthen context, but it still does not guarantee an event.
