吠舍的自然职责是农耕、畜牧和贸易。首陀罗的自然职责则是服务。
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.
当一个人按照自己的阶层和生命阶段正确履行职责时，他的心会得到净化，他会升入天堂。《阿帕斯坦巴法经》（Apastambha Dharma Sutra）宣称：“不同阶层和阶段的人，各自忠于自己的职责，死后收获其行动的果报，然后通过剩余的业（Karma）获得更优越的法（Dharma）、寿命、学识、品行、财富、幸福和智慧的出生。”《往世书》（Puranas）中也有生动的描述，说明了四个阶层和阶段的人通过履行各自职责所获得的不同结果和世界。
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.
