Just like moons and like suns, / With the certainty of tides, / Just like hopes springing high, / Still I'll rise.

Our reading
An editorial interpretation.
Angelou reaches for the moon, the sun and the tides because they always return. Her rising feels just as certain as theirs. Hope, in this view, springs back up no matter what pushes it down.
