It's really important to control your thought and not let in any fearful, hateful, or "not good feeling" thoughts into your consciousness.
The real battle we have is with ourselves. And more specifically our own minds.
Death is nothing more than doing away with a dream of a particular ego. There is no way to kill or be killed because we are spiritual beings.
There is nothing either good or bad, but thinking makes it so.
The happiness of your life depends upon the quality of your thoughts... therefore guard them accordingly.
Think on lovely things that feel good.
Sweet are the uses of adversity;
Which, like the toad, ugly and venomous,
Wears yet a precious jewel in his head.
The very circumstance, which your suffering sense deems wrathful and afflictive, Love can make an angel entertained unawares.
