BG Chap 18 - Achieiving perfection following varṇāśrama

By following his qualities of work, man achieves complete success. This is because engaging in these activities according to one’s varṇa and āśrama, gives rise to knowledge. Men achieve steadiness in knowledge by worshiping the Lord, who is the source of all beings and who is all pervading, thru mentally offering their prescribed duties. The Supreme Lord, by His two energies, His external energy and internal energy, is all-pervading. Therefore one should worship the Supreme Lord with His energies. Generally the Vaiṣṇava devotees worship the Supreme Lord with His internal energy. Worshiping the Lord who is situated as the soul of all the devatās by one’s activities – offering the actions to Him after performing them – by thinking ‘May the Lord be satisfied with the act’, men attain perfection. Everyone should think that he is engaged in a particular type of occupation by Hṛṣīkeśa, the master of the senses. And by the result of the work in which one is engaged, the Supreme Personality of Godhead, Śrī Kṛṣṇa, should be worshiped. If one thinks always in this way, in full Kṛṣṇa consciousness, then, by the grace of the Lord, he becomes fully aware of everything. That is the perfection of life
