Trapped Blessings

A close friend of mine shared something beautiful with me. Visualize this:

Anything you want - be it refua, parnassah, zivug, shalom bayit, etc. - is 'trapped' inside a treasure box in Shamayim. The key is already in the lock on the treasure box. All you need to do is turn the lock to open the treasure box and receive the brachot!
Your tefillot are the force to turn the key.
Through sincere, powerful tefillah -- one can expect to have enough power to turn the key.
