The Kabbalah teaches us that thoughts like clouds precursing the rain to come down, if filled with happiness then happiness rains down, if filled with fear, then fear comes down.
Obviously you may wonder, can this be?
Is not reality independent of something as small as a thought?
But reality is only a single thought from God.
A thought creates reality.
In fact, your thoughts are also part of God’s reality though they can create a new reality.
Imagine a drop of rain, where did it come from?
It came from below!
So your drop of positive or negative thinking, elevates into the clouds that becomes your destiny.
