If you look at me, your eye consciousness forms an image, but makes no judgement such as 'This is my friend.' Close your eyes and a mental image remains. Joy and wisdom function on that mental level; peace of mind is achieved through mental training. The love and compassion common to all major religions and their teachings about tolerance and patience also relate to training the mind.

Collective responsibility can be learned. We need something like a map of the mind and emotions so we can practise a kind of emotional hygiene. We can learn from our own experience—this emotion leads to that result. We can identify which emotions are destructive and what their causes are. Just as we study in school or college, we need a scientific approach. Understanding the mind and emotions can help us all.
