Acharya Prashant explains that passion is not a feeling of being an outsider or a state of thirst; rather, it is an inner fullness where one acts for the sake of the act itself, not for a result or satisfaction. He defines passion as the mind's orientation toward the truth, characterized by the realization that the truth is one's destiny and is never far away. True passion requires two conditions: an absolute love for the object and the absolute security that the object can never be taken away. He uses the metaphor of a fish and the ocean to illustrate this inseparable and secure relationship, noting that worldly love often fails because it lacks either genuine love or a secure foundation.
