Destiny.

"Destiny comes suddenly, bringing concern; she stares at you with horrible eyes and clutches you at the throat with sharp fingers and hurls you to the ground and tramples upon you with ironclad feet; then she laughs and walks away, but later regrets her actions and asks you through good fortune to forgive her. She stretches her silky hand and lifts you high and sings to you the Song of Hope and causes you to lose your cares. She creates in you a new zest for confidence and ambition. If your lot in life is a beautiful bird that you love dearly, you gladly feed to him the seeds of your inner self, and make your heart his cage and your soul his nest. But while you are affectionately admiring him and looking upon him with the eyes of love, he escapes from your hands and flies very high; then he descends and enters into another cage and never comes back to you.

What can you do?
Where can you find patience and condolence?
How can you revive your hopes and dreams?
What power can still your turbulent heart?"

~Spirits Rebellious By Khalil Gibran
