Be careful with your words, because words are reality. This includes thought. The eyes are a weapon. Your words and thoughts are expressed though your eyes, whether good or evil.
Humans are both rational and irrational. These characteristics are like wings – you need two to fly. If only one aspect is focused on, the other becomes weak, thus pulling the person off balance. If one drives the other, disaster or insanity can result.
Just imagine one wing being strong – the rational side, for example. If the rational person insists on submerging his/her irrational process, the irrationality WILL come out in some other way – often in a political context. Politics is, IMO, inherently irrational.
Pure irrationality results in simpletons or fanatics. They need some rationality to bring them back to earth.
This idea of balance needing the two wings of thought is not a new idea, just my words which came to me while listening to Chassidic music. Have you ever wondered why so many religious people are calm and happy? It is because they have found The Balance.
This is true for all religions, some more than others. Enjoy this nigun, often translated as wordless prayer, here translated as tune.
