Money, bondage or freedom
For the one unclear about the real purpose of his life, money is the means to consume, to splurge, to satiate your impulses, to gather possessions you may not even be in need of. And caught in the web of ever increasing needs and desires, money quickly becomes a means of bondage.
For the wise, money is a resource that if saved for and deployed carefully can not only meet your genuine material needs but also give you the freedom to choose what you want to do with you life. Money for the wise is the means to liberation.
