Upon your lonely journey I accompany you, whether you travel through endless mountains or seas of blue. Wherever you go, I keep your place. Lost you're not, when I'm embraced. What am I?
I am heavy forward, but backward I'm not. What am I?
After you go through a fall, I will take over. All life will stall, or at least grow slower. What am I?
I'm the source of all emotion but I'm caged in a white prison.
