Duality is the real root of our suffering and of all our conflicts. All our concepts and beliefs, no matter how profound they may seem, are like nets which trap us in dualism. When we discover our limits we have to try to overcome them, untying ourselves from whatever type of religious, political, or social conviction may contain us. We have to abandon such concepts as 'enlightenment', 'the nature of the mind', and so on, until we no longer neglect to integrate our knowledge with our actual existence.
