The ultimate goal of life is Viṣṇu, Kṛṣṇa. Therefore, either by Vedic regulative principles or by materialistic activities, if one tries to reach the destination of Kṛṣṇa, that is the perfection of life. Kṛṣṇa should be the target; everyone should try to reach Kṛṣṇa, from any position of life.

Kṛṣṇa accepts service from anyone. The Lord says in Bhagavad-gītā (9.32) :

māṁ hi pārtha vyapāśritya ye ’pi syuḥ pāpa-yonayaḥ striyo vaiśyās tathā śūdrās te ’pi yānti parāṁ gatim

“O son of Pṛthā, those who take shelter in Me, though they be of lower birth — women, vaiśyas [merchants], as well as śūdras [workers] — can approach the supreme destination.” It does not matter what one’s position is; if one aims at reaching Kṛṣṇa by performing his occupational duty under the direction of the spiritual master, his life is successful. It is not that only sannyāsīs, vānaprasthas and brahmacārīs can reach Kṛṣṇa. A gṛhastha, a householder, can also reach Kṛṣṇa, provided he becomes a pure devotee without material desires. An example of this is cited in the next verse.
