One hundredth day

Of late, I've taken to accompanying each Ave in the fourth decade with a prayer for an everlasting perfection. They change day to day but there are some I pray every day (okay, you got me: I mean every day I make it to the fourth decade--most days).

For example,

{(tacit) Jesus, through the Immaculate Heart of Mary,} grant her perfect everlasting peace.

This requires no further explanation. We mean what the church means by peace in the prayer resquiat in pace.
