Answer:
I bind it and it walks. I loose it and it stops.
What can you share and still have all for yourself?
I weaken all men for hours each day. I show you strange visions while you are away. I take you by night, by day take you back. None suffer to have me, but do from my lack.
I build up castles. I tear down mountains. I make some men blind. I help others to see.
When Iām metal or wood, I help you get home. When Iām flesh and Iām blood, In the darkness I roam.
I am the fountain from which no one can drink. For many I am considered a necessary link. Like gold to all I am sought for, but my continued death brings wealth for all to want more.
