Acharya Prashant explains the concept of being an 'apparent cause' as mentioned by Shri Krishna in the Bhagavad Gita. He describes it as a state where the personal ego is no longer the center of operation, and the individual allows their system to be governed by an impersonal, divine power. Usually, the body-mind complex is commanded by the ego, which is an improper master because it is dependent on and identified with the body. This identification prevents the ego from pushing the body toward great endeavors or missions that do not serve bodily interests. When the ego is the driver, it resists any effort that causes physical discomfort or goes against personal attachments.
