God's love for humankind is akin to that of a parent toward their children. As a result, it was an expression of God's parental love to endow humankind with divine attributes, including the attribute of creativity.
The Principle Of Creation in Divine Principle cites Genesis (1:28) as part of God's plan to establish an ideal world through the fulfillment the Three Blessings: Be fruitful, multiply, and to take dominion over creation. Hence, the second and third Blessings encompass the attribute of creativity. In this respect the Creator endowed humankind with perhaps the most elemental aspect of his Deity—the ability to be a co-creator. Thus, any artistic endeavor can be considered a manifestation of ones divine character as a son or daughter of God.
In this context, Clara Schumann's views regarding the art of composing is in accord with her divine purpose when she states, "Composing gives me great pleasure...there is nothing that surpasses the joy of creation, if only because through it one wins hours of self-forgetfulness, when one lives in a world of sound."
The joy of creating, or more accurately, being a co-creator with God and in accordance with God's principle of creation, is predicated on the Unificationist ideal of experiencing God's, and one's own divinity, though an act of creativity—in Clara Schumann's case, composing music.
The idea of experiencing joy through attaining a condition of "self-forgetfulness" is concomitant with attaining joy through public service and "living for the sake of others." Schumann's devotion to her husband and family (she gave birth to seven children), while sacrificing her personal aspirations, is a testament to her commitment to the ideals of "true love." Her loving support of her husband's music and career remains a significant aspect of her legacy.
By living in a selfless manner, one becomes the beneficiary of "heavenly fortune," a condition whereby God's blessings are bestowed upon those who willingly offer themselves to the greater good. That Clara Schumann continued to develop her career and pursue her artistic aspirations with great success attests to the blessing of "heavenly fortune" being evident in her life and work.
Though her composing endeavors would diminish in her later years, she became a pioneer in the realm of women composers who had achieved relatively little recognition in her time. This belies the idea that musical composition was exclusively province of men. Her accomplishments as a composer and performer attest to the ideal that co-creativity with God transcends external attributes such as gender, race, ethnicity, and societal constructs.
