By making a steady effort, I think we can overcome any form of nagative conditioning and make positive changes in our lives. But you still need to realise that genuine change doesn’t happen overnight.
All deluded states of mind, all afflictive emotions and thoughts, are essentially distorted, in that they are rooted in misperceiving the actual reality of the situation. No matter how powerful, deep down these negative emotions have no valid foundation. They are based on ignorance. On the other hand, all the positive emotions or states of mind, such as love, compassion, insight and so on, have a solid basis. When the mind is experiencing these positive states, there is no distortion.
