It should be known that at the beginning of the dynasty, taxation yields a large revenue from small assessments. At the end of the dynasty, taxation yields a small revenue from large assessments.
The reason for this is that when the dynasty follows the ways (sunan) of the religion, it imposes only such taxes as are stipulated by the religious law, such as charity taxes, the land tax, and the poll tax. They mean small assessments, because, as everyone knows, the charity tax on property is low. The same applies to the charity tax on grain and cattle, and also to the poll tax, the land tax, and all other taxes required by the religious law. They have fixed limits that cannot be overstepped.
When the dynasty follows the ways of group feeling and (political) superiority, it necessarily has at first a desert attitude, as has been mentioned before. The desert attitude requires kindness, reverence, humility, respect for the property of other people, and disinclination to appropriate it, except in rare instances. Therefore, the individual imposts and assessments, which together constitute the tax revenue, are low. When tax assessments and imposts upon the subjects are low, the latter have the energy and desire to do things. Cultural enterprises grow and increase, because the low taxes bring satisfaction. When cultural enterprises grow, the number of individual imposts and assessments mounts. In consequence, the tax revenue, which is the sum total of (the individual assessments), increases.
