One must accept both the joys and sorrows of life with equanimity and grace from "summary" of The Consolation of Philosophy by Boethius,
The wise man, my dear friend, is he who understands the true nature of life and accepts it with equanimity and grace. Life, as we know, is a mixture of joy and sorrow, pleasure and pain. It is like a wheel that turns, sometimes lifting us to great heights, and at other times, bringing us down to the depths of despair. The key to living a content and peaceful life lies in embracing both the good and the bad with a calm and steady heart. When fortune smiles upon us, we must not become arrogant or complacent, for we know that the wheel of fortune is ever-turning, and our fortunes may change in an instant. Likewise, when misfortune befalls us, we must not despair or lose hope, for we know that even the darkest night will eventually give way to the light of dawn.
To be truly wise is to see beyond the transient nature of both joy and sorrow, to understand that they are but two sides of the same coin. Just as the river cannot always flow with smooth waters, so too must we accept the ebb and flow of life with equanimity and grace.
It is in this acceptance that we find true freedom and peace of mind. For when we stop clinging to the fleeting pleasures of life, we are no longer at the mercy of its pains and sorrows. Instead, we become like the steady oak tree that stands firm in the face of the storm, unshaken by the winds of fate.
So let us learn to embrace both the joys and sorrows of life with equanimity and grace, knowing that they are but passing clouds in the vast sky of existence. In doing so, we can attain true wisdom and inner peace, and live our lives with dignity and serenity.
