This sentence came from Tagore's " A Collection of Birds ", a famous poem. The theme of the poem was the flying bird, which expressed the desire for freedom and pursuit, as well as the thought of fate. The meaning of this sentence is that even if we lose something, we may also lose something else, and these things may be more important than losing what we originally lost. If we shed tears, we lose the good, but we also lose the bad, which may be more precious than the loss of the sun and the stars. This sentence expressed a balanced and rational thinking by comparing loss and gain. It tells us that there are not only two states of gain and loss in life, but there are many different factors and things that affect our entire life. Therefore, we should cherish what we have more and learn to balance and deal with all kinds of complicated relationships.
