In this verse, Krishna addresses the common human inclination toward immediate gratification through the worship of celestial beings (devas). The 'success' (siddhi) mentioned here refers to the fulfillment of material desires—wealth, status, health, or sensory enjoyment—attained through ritualistic action. Krishna acknowledges that the human realm is uniquely suited for such outcomes because human life is defined by 'karma,' or action-based causality. Because the human condition is characterized by a high degree of free will and the capacity for purposeful ritual, the fruits of one's actions manifest here with significant speed compared to other planes of existence. However, there is an underlying warning: by focusing on the 'fruits' (phala) of action through the mediation of deities, the seeker remains bound to the cycle of desire. Krishna is not condemning the worship of gods, but rather highlighting the finite nature of these gains. He invites Arjuna to contemplate why one would settle for perishable, sensory rewards when the eternal nature of the Self is within reach. This serves as a psychological diagnosis of the ego, which naturally seeks quick external validation, and sets the stage for Krishna’s subsequent teaching on nishkama karma (selfless action), where the focus shifts from the result to the act as an offering to the Divine. By understanding that these material successes are transitory, the seeker is gradually encouraged to pivot from the pursuit of temporary 'siddhi' to the attainment of permanent liberation (moksha).

While human life offers the unique capacity for rapid material success through ritual action, true wisdom lies in transcending the desire for these perishable fruits in favor of divine realization.
