Rabbi Yisroel Baal Shem Tov the founder of Chassidus and eventually Chabad had as guiding light, inspiring his every moment the following teaching from his father the Tzaddik Rabbi Eliezer: Fear No One And Love Everyone With All Your Heart And Soul!
He certainly fulfilled this in his lifetime and managed to inspire millions of Jews in his and subsequent generations!
Fear is a funny thing, for we have but one computer, one cpu, that processes our thoughts in our brain.
You are your soul, the feeling that feels fear or love, the entity that sees your thoughts, now the way your soul works is that it doesn’t really enter your body, rather is associated to it and sort of hovers in and around it, so you a. can feel fear and b. this will cause you to think of ways to prevent fear.
Likewise, you can feel love and this will cause you of ways to think of how to obtain your desires.
But you can’t feel fear and love at the same time.
So normally we begin life – hopefully – in love with the world.
Then we have some kind of traumatic incident and we fall out of love with life, where the basic saying of Henry David Thoreau
“The mass of men lead lives of quiet desperation. What is called resignation, is confirmed desperation;” applies.
So the first thing we must realize is, that our brain is not truth; like our computer is not truth, it merely plays what we tell it to play (determined by our feelings which enter our brain and try to prevent our fears or achieve our loves.)
So there really is, one solution: Fear No One And Love Everyone With All Your Heart And Soul!
