Apart from other living entities, the living being in the human form of body is systematically controlled by the Vedic injunctions in terms of the divisions of varna and asrama. A human being is expected to follow the rules and regulations of varna and asrama; otherwise he cannot escape punishment by Yamaraja. The point is that every human being is expected to elevate himself to the position of a brahmana, the most intelligent man, and then one must transcend that position to become a Vaisnava. This is the perfection of life. The brahmana, ksatriya, vaisya and sudra can elevate themselves by worshiping the Lord according to their activities (sve sve karmany abhiratah samsiddhim labhate narah). The divisions of varna and asrama are necessary to insure the proper execution of duties and peaceful existence for everyone, but everyone is directed to worship the Supreme Lord, who is all-pervading (yena sarvam idam tatam). The Supreme Lord exists vertically and horizontally (otam protam), and therefore if one follows the Vedic injunctions by worshiping the Supreme Lord according to ones ability, his life will be perfect. As stated in Srimad-Bhagavatam (1.2.13):

The words namabhir vaci are very important. In the varnasrama institution, there are different namesbrahmana, ksatriya, vaisya, sudra, brahmacari, grhastha, vanaprastha and sannyasi. The vak, or Vedic injunctions, give directions for all these divisions. Everyone is expected to offer obeisances to the Supreme Lord and perform duties as indicated in the Vedas.
