Yichudim — Unificationsיחודים

The signature Lurianic meditation: interweaving two divine names letter by letter (most famously YHVH and Adonai, yielding the fusion YAHDVNHY) to unite the hidden and revealed faces of divinity — performed within prayer, at graves of the righteous (Luria prescribed specific yichudim for communing with sages' souls), and at the hinges of the day. Acting on the axiom that separateness is repairable.
