People do not understand what is mokṣa, what is economic development, what is religious principle. There is no education. So unless there is sufficient education on these principles—dharma, artha, kāma, mokṣa—you cannot have peaceful life in human society. That is not . . . that is animal society. Dharmeṇa hīnāḥ paśubhiḥ samānāḥ (Hitopadeśa). If there is no principles of life, that is animal society. Unfortunately, at the present moment, the education is simply for sense gratification. That is animalistic education. Therefore, in spite of advancement of so many things, people are not happy. People are not happy.
So here it is said, caturbhir vartase yena pādair loka-sukhāvahaiḥ. Sukhāvahaiḥ. Sukha means happiness. If you want to increase happiness . . . everyone wants to become happy. That is the highest principle.
