Blinded

Humans do not see what they want to see and hear what they want to hear. In other words, they fail to accept the truth that they see everyday, and instead, they make their own illusions for personal satisfaction. And such illusion is very hard to be satisfied because they are mostly selfish and greed motivated. That's why they continue to feel dissatisfied, continue to have desire, and continue to live in their own self-made world of unfulfilled illusion.
