Dasha Sandhi
Dasha sandhi is the junction between two planetary periods — the handover months when one long chapter ends and another begins
Dasha sandhi is the junction between two planetary periods — the handover months when one long chapter ends and another begins. Tradition treats these seams as tender: good times to consolidate, poor times to force. A life in Vedic astrology unfolds in chapters, each ruled by a planet for a span of years — the dashas. Where two chapters meet, the old ruler is handing over and the new one has not yet settled in, and that seam is the dasha sandhi. Like the last days of one job and the first of the next, it can feel unanchored: energy scattered, direction unclear, results from either period arriving unevenly. The tradition watches these junctions with care — most of all when the two planets are unfriendly or very different in nature — and counsels treating them as transitions to move through rather than moments to launch something that needs firm ground. It is less a warning of harm than a reminder that endings and beginnings overlap: a season to tie off loose ends and let the new chapter find its feet before asking too much of it.
The sandhi of mahadashas — especially between inimical or sharply different lords — is observed with care in the timing tradition; undertakings begun in the seam inherit its instability.
