In the end, people become neurotic. Why? Because they don't know. They just follow their moods and don't know how to look after their own minds. When the mind has no one to look after it, it's like a child without a mother or a father. An orphan has no refuge, and without a refuge, he is very insecure. Likewise, if the mind is not looked after, if there is no training or maturation of character with right understanding, it's really troublesome.(From A Tree In a Forest)
