I had lot of thought about perception and vision. What I conclude is that we always see what we want to see. With time we learn to ignore things and our sense get biased to our opinions and thoughts.
With this biased vision or perception we fail to recognise Omens but realise that only when time has gone.
I'm not sure if we can unlearn all those tricks of ignorance.
But in other thoughts I feel that ignorance is also one of the great power we have. Perhaps we need not process/interpret all we see but should look for patterns or signals. I fee we should develop our sense for critical perception.
I"m still figuring out the way.
