Don't cry when the sun is gone, because the tears won't let you see the stars.

The line counsels resilience after loss: when something bright and sustaining (the “sun”) disappears, grief is natural, but fixation on sorrow (“tears”) can block perception of what remains—new possibilities, consolations, or beauty (“stars”). Its power comes from the simple astronomical metaphor: night is not only absence of day but a different kind of visibility. Read this way, the quote encourages a shift from mourning what has ended to attending to what can still be seen and valued, without denying that the ending hurts.
