Question: Is it true that most of the times what we suffer from is not reality but our illusions and false hopes, the way we want to see the things as opposed to how they are?
Answer: Yes, it is true. There is no actual reality, only an illusory world we paint for ourselves based on our own desires, states, moods.
If we want not to suffer, if we want to sense ourselves in a better world, all we have to do is changing ourselves, change our own qualities, aspirations.
