I couldn't decide on one, so I'm sharing a section of the Four Quartets on each of the four High Holy Days. Read the whole thing though (link in title), Eliot is amazing.
Burnt Norton [excerpt]
Yet the enchainment of past and future
Woven in the weakness of the changing body,
Protects mankind from heaven and damnation
Which flesh cannot endure.
Time past and time future
Allow but a little consciousness.
To be conscious is not to be in time
But only in time can the moment in the rose-garden,
The moment in the arbour where the rain beat,
The moment in the draughty church at smokefall
Be remembered; involved with past and future.
Only through time time is conquered.
