If we trust and we are betrayed - who is really hurt? Has our trust been destroyed, or just our connection with that person. Is it not the betrayer who is actually hurt in this scenario?
Trust creates a situation in every case where all business dealings can be smoothly transacted, where things can go quickly, where things can be built on a solid foundation of friendship and connection. In business if you do not trust .. then any agreements which you make are destined to fall apart - because they are built on quicksand.
In a relationship if you do not trust, you are projecting out images of the other betraying you.. and what else can happen but that betrayal?
In fact if you do not trust you are responsible for creating a situation where your lack of trust is demonstrated to be true.
So what's the lesson in all of this.. I say keep a basic trust in your heart for in this way, you will attract to yourself that which is open and heartful.
You may be deceived if you trust too much, but you will live in torment if you do not trust enough
