吠舍 (Vaiśya) 的自然職責是農業、畜牧業和商業。首陀羅 (Śūdra) 的自然職責則是服務。
The natural duties of the Vaisyas are agriculture, cattle-rearing and trade. Of the Sudras, too, the natural duty is in the form of service.
當一個人根據自己的種姓和生命階段正確履行職責時，他的心靈會得到淨化，他會升入天堂。「阿帕斯坦巴法經 (Apastambha Dharma Sutra)」宣稱：「各個種姓和階層的人，各自專注於其職責，死後收穫其行為的果報，然後透過殘餘的業 (Karma) 獲得更高尚的法 (Dharma)、壽命、學識、品行、財富、幸福和智慧的轉世。(2.2.2.3)」在往世書 (Purāṇas) 中也有生動的描述，說明四種種姓和階層的人透過履行各自職責所獲得的不同結果和世界。
When a man performs his duties rightly according to his caste and order of life his heart is purified and he goes to heaven. Apastambha Dharma Sutra declares? Men of severla,castes and orders? each devoted to his respective duties? reap the fruits of their actions after death? and then by the residual Karma attain to births in superior Dharma? span of life? learning? conduct? wealth? happiness and intelligence (2?2?2?3). There is a vivid description in the Puranas also of the different results and worlds which men of the four castes and orders obtain by discharging their respective duties.
