Every day, you automatically and instinctively put keys into locks, without seeing that when you do you are symbolically replicating the work of the spirit (the key) in matter (the lock). So, resolve to study what a key and a lock are, and you will have the keys to open locks you had never imagined.
Yes, your ears, mouth, nostrils and eyes are all locks, and the brain itself is a lock. Once you understand that, you will be in possession of keys that open the doors of nature as well as doors within yourself. And what are the mind, the heart and the will? Doors that give access to regions where we think, feel and act, and the keys for opening these doors are wisdom, love and truth.
Wisdom opens the mind, love opens the heart, and truth opens the will. When you have a problem, try these keys. And if you don’t succeed with the first, try the second. And if the second doesn’t work either, try the third. If you know how to proceed, one of these keys is bound to solve your problem.
