This blessing can be recited as we light the candles to begin the Passover Seder and to celebrate the arrival of spring:

Blessed is the light in the world.
Blessed is the light within humanity.
Blessed is the light of Passover.

Barukh ha-or ba-olam
Barukh ha-or ba-adam
Barukh ha-ror ba-Pesakh

(If this blessing is different or new to you: Judaism is a constantly evolving conversation, practice, and identity. This text has been used by tens of thousands of Jews over the past fifty years.)
