Along with solitude, sadness can act as a fertilizer for our personal growth if we let it. In his Letters to a Young Poet, Rilke writes about how our sadnesses should be trusted more than our joys, for something invisible to the eye is happening inside of us when we are sad, something we need to pay attention to that will transform us and the way we move through the world:
Perhaps many things inside you have been transformed; perhaps somewhere, someplace deep inside your being, you have undergone important changes while you were sad. The only sadnesses that are dangerous and unhealthy are the ones that we carry around in public in order to drown them out with the noise; like diseases that are treated superficially and foolishly, they just withdraw and after a short interval break out again all the more terribly; and gather inside us and are life, are life that is unlived, rejected, lost, life that we can die of. If only it were possible for us to see farther than our knowledge reaches, and even a little beyond the outworks of our presentiment, perhaps we would bear our sadnesses with greater trust than we have in our joys. For they are the moments when something new has entered us, something unknown; our feelings grow mute in shy embarrassment, everything in us withdraws, a silence arises, and the new experience, which no one knows, stands in the midst of it all and says nothing.
That is why the sadness passes: the new presence inside us, the presence that has been added, has entered our heart, has gone into its innermost chamber and is no longer even there, is already in our bloodstream. And we don’t know what it was. We could easily be made to believe that nothing happened, and yet we have changed, as a house that a guest has entered changes. We can’t say who has come, perhaps we will never know, but many signs indicate that the future enters us in this way in order to be transformed in us, long before it happens. And that is why it is so important to be solitary and attentive when one is sad: because the seemingly uneventful and motionless moment when our future steps into us is so much closer to life than that other loud and accidental point of time when it happens to us as if from outside. The quieter we are, the more patient and open we are in our sadnesses, the more deeply and serenely the new presence can enter us, and the more we can make it our own, the more it becomes our fate; and later on, when it “happens” (that is, steps forth out of us to other people), we will feel related and close to it in our innermost being. And that is necessary.
He reiterates his belief that equanimity—an acceptance of all aspects of our life, sadness and solitude and joy—will help us grow and become who we are truly meant to be. We don’t even have to name the thing inside of us or force it to grow us before it’s time; it is better to let it do its work and for us to embrace difficulty more than ease for the growth that comes out of it:
So you mustn’t be frightened… if a sadness rises in front of you, larger than any you have ever seen; if an anxiety, like light and cloud-shadows, moves over your hands and over everything you do. You must realize that something is happening to you, that life has not forgotten you, that it holds you in its hand and will not let you fall. Why do you want to shut out of your life any uneasiness, any misery, any depression, since after all you don’t know what work these conditions are doing inside you? Why do you want to persecute yourself with the question of where all this is coming from and where it is going? Since you know, after all, that you are in the midst of transitions and you wished for nothing so much as to change. If there is anything unhealthy in your reactions, just bear in mind that sickness is the means by which an organism frees itself from what is alien; so one must simply help it to be sick, to have its whole sickness and to break out with it, since that is the way it gets better. In you… so much is happening now; you must be patient like someone who is sick, and confident like someone who is recovering; for perhaps you are both. And more: you are also the doctor, who has to watch over himself. But in every sickness there are many days when the doctor can do nothing but wait. And that is what you, insofar as you are your own doctor, must now do, more than anything else.
Don’t observe yourself too closely. Don’t be too quick to draw conclusions from what happens to you; simply let it happen…. The extraordinary circumstances of a solitary and helpless childhood are so difficult, so complicated, surrendered to so many influences and at the same time so cut off from all real connection with life that, where a vice enters it, one may not simply call it a vice. One must be so careful with names anyway; it is so often the name of an offense that a life shatters upon, not the nameless and personal action itself, which was perhaps a quite definite necessity of that life and could have been absorbed by it without any trouble…. I see that it is now yearning forth beyond the great thing toward the greater one. That is why it does not cease to be difficult, but that is also why it will not cease to grow.
