Any action performed with the feeling of ego, the sense that I did it , or with the sense of attachment, that it is my act, can only bring sorrow to you in the end. Such actions will always result in further bondage. However, when you transform your actions into yoga , then you become free from bondage. All actions performed as offerings to the divinity, without any sense of individual doership and without seeking any personal results, will be transformed into yoga .
Numerous troubles arise when one acts with a feeling of egoism.
Inwardly, you might feel, 'This action was performed by me, so I should derive the benefits from this action. I worked, so I deserve to get paid. Such feelings serve only to further strengthen the sense of ego, the sense of I and mine. As this sense of I and mine goes on increasing, the atma goes further and further into obscurity, and the joy emerging from the atma goes on decreasing. To destroy egoism completely, Krishna asked Arjuna to transform all his actions into yoga .
