Tack us on at the end of your triumphal processions

Jesus, be the Paschal joy that remains in our hearts throughout the year, and attach us, reborn by grace, to your triumphs.

Esto perenne mentibus
Paschale, Iesu, gaudium
et nos renatos gratiae
tuis triumphis aggrega.

     Stanza 6 of the pre-11th-century (?) Laetare, caelum, desuper, translation (with italics) mine.  I have not done any research into this one.  For "triumphs" read "triumphal processions."  But why that is plural I don't know, unless the triumphi in question are (and this would make a lot of sense) "perennially" liturgical in nature (as with, at Easter itself, the newly baptized in train).
