The Illogical us
You might have wondered and awe at how logical a creature the human beings are. What if you realize it aint so.
The next time you make a decision or come to a conclusion, think about it. In mostly likelihood you would have made the judgement right at the start and then just assimilated those facts that apparently lead to a logical conclusion to your judgement. You don't see the rest which disprove it.
Interestingly we apply our mind only after we have a thought. Once you have a thought it either creates a chain reaction in you or outside of you both potentially leading to something undesireable.
So they urge humans to train themselves to apply / put your mind before your thought. If only we could understand this well we could plausibly be better at not being led by our thoughts.
