An observation, not necessarily correct.
People who want to pass on their family name or leave a mark in history are actually afraid of death, afraid of their own disappearance. They want a part of themselves to remain in this world after death because of their attachment and love for the world. People who want love actually want to connect with another person, often to escape loneliness. Those who seek fame are actually lacking in love, needing attention and love from many people. Those who seek material gain generally lack a sense of security, needing a lot of money to ensure they do not fall into material scarcity. Those who want nothing and lack nothing may fall into depression if male, or act recklessly if female. In Wang Xiaobo's novel "The Lover" the emperor is described as "He lacks nothing, so he developed a mild depression." The girl Xiaoqing is described as "She lacks nothing, so she acts recklessly." The emperor in the palace represents the elimination of material scarcity, while the girl in the deep mountains represents spiritual fulfillment.
Most people are in a state of lack, which is relative to desires. When lack is eliminated and desire extinguished, you will see a state of deficiency in the soul - emptiness, which is the default state created by God. The state of lack is stable, while the state of deficiency resulting from the elimination of lack is an extremely unstable psychological state, like being at the highest point on a sphere, not knowing where it will slide next. Many so-called abnormal psychological states originate from here, and because these states are rare, they are considered abnormal, while the common state of lack is considered normal. In the eyes of the Creator, there is no normal or abnormal. Why were there fewer people with psychological issues in the past when material and spiritual wealth were lacking, and now, in an age of increasing material and spiritual wealth, there are more people with psychological issues? It is because more people have eliminated lack and reached an extremely unstable psychological state. This state of deficiency and extreme psychological state actually appears frequently in our lives - if you observe carefully, it is fleeting, but if you can linger in that state for a long time, you will discover and experience a world different from the past and from most people.
