When a person performs actions in accordance with their own nature and dharma—their station in life, whether as a student, householder, or other stage of existence—the desires and vasanas accumulated from past actions gradually dissolve. This cessation of desire, and the resulting purification and peace of mind, becomes possible only when one learns to act by surrendering the ego and offering all deeds to the Divine.
In worldly affairs, we observe this principle: it is our duty to serve the source from which we receive the power to act and the fruits of our labor. For example, those in government service have the duty to fulfill their responsibilities for the government, for it is the government that grants them the authority to work and provides their livelihood. If someone forgets the power of that government and uses their position for selfish gain, such action becomes binding and enslaving. Conversely, when one acts with the spirit of offering, there is no bondage; instead, one advances and prospers. Similarly, we must perform our duties while remembering the Supreme Divine, from whom we have received our senses, mind, and all our faculties and their capacities. The fulfillment of our duty becomes worship of the Divine. In this verse, Lord Sri Krishna teaches that all people, regardless of their station and stage of life, should worship the Supreme Self—the cause of all creation—through the faithful performance of their duties.
When one acts with the spirit of offering to the Divine, ego is entirely dissolved. In the absence of ego, past vasanas are destroyed, and new binding desires do not arise. Thus, according to the law of karma, one receives the worldly fruits of action, but beyond that, one also attains purification of mind. Only the person whose inner being is purified can experience the nature of the Supreme Self. This is true perfection.
In this way, we see that when the spirit of worship enters into the performance of one's duty, one's very workplace becomes a temple or sacred pilgrimage site.
Perfection can be attained only through the faithful performance of one's own dharma. Therefore...
