Maturity - among other things, the unclouded happiness of the child at play, who takes it for granted that he is at one with his play-mates.

The quote by Dag Hammarskjold, "Maturity - among other things, the unclouded happiness of the child at play, who takes it for granted that he is at one with his play-mates," reflects on the concept of maturity through the lens of childhood. Hammarskjold suggests that maturity isn't just about age or experience, but about the ability to embrace happiness with the simplicity and purity of a child. The unclouded happiness he describes refers to the carefree, spontaneous joy a child feels while playing, free from the complexities and worries that come with adulthood.

In the quote, Hammarskjold emphasizes the connection and unity children experience when they interact with their playmates. A child doesn’t question their bond with others—they take it for granted that they are one with those around them, sharing a common moment of joy. This innocent perspective is something often lost as people grow older and become more entangled in their own thoughts, insecurities, and individual concerns.

Hammarskjold contrasts this pure childhood joy with the often clouded or more complicated emotions that come with adulthood. As we mature, we may lose the ability to experience such unreserved happiness, weighed down by external expectations, responsibilities, or the realization of life's complexities. Yet, he suggests that part of true maturity lies in recapturing this childlike sense of joy and connectedness with others.

The origin of the quote lies in Hammarskjold's broader reflections on the human condition, particularly his thoughts on the inner peace and simplicity that one should aim for in life. Known for his spiritual and philosophical insights, Hammarskjold often explored the idea of personal growth and how maturity isn’t just about acquiring wisdom but about staying attuned to the simple, authentic aspects of life that bring true contentment.
