“When we see something that we want and are able to get it, there is no Duḥkha.
If we are unable to to get it, this is the beginning of Duḥkha.
Very often people have this type of Duḥkha even when they are trying to improve their lives.
They become so thirsty for understanding that they are unable to get understanding as quickly as they desire.”
