The combination of affluence and secularism produces boredom as surely as the combination of hydrogen and oxygen produces water. Without affluence, people have a built-in purpose: obtaining food and shelter, supporting oneself and one’s family, etc. And religion, with or without affluence, likewise has always provided people with meaning. Without religion, therefore, purpose is often lost. Add to that the number of people who are not married and do not have children (also a result of the combination of affluence and secularism) and you remove another universal source of meaning.
Consequently, all who are or have been, or will be assembled on earth, have a common purpose. Absolute uniformity prevails among men so far as their fundamental purpose is concerned.
Likewise, the destiny of all the spirits sent to earth, is the same.
