Answer
Qualities like determination and focus certainly exist—even in those who have no connection with Krishna. But when these qualities are applied to temporary goals, their foundation is unstable. One may be highly driven for success, power, or recognition, yet the very platform they stand on is uncertain. Today they may be at their peak; a few years later, circumstances can completely change.
Such determination often operates on the mental plane—what the Srimad Bhagavatam describes as manoratha, the chariot of the mind. On this platform, everything can shift quickly. Opinions change, priorities change, and even strong convictions can reverse overnight. We see this in public life as well—leaders may strongly advocate one position today and abandon it tomorrow, driven by underlying desires for power or sense gratification.
Desire is the driving force. When desire is strong, a person can show great intensity and discipline. But if that desire is rooted in temporary gains—wealth, fame, control—then the determination itself becomes unsteady. One may remain committed to the goal (like power or success), yet constantly shift methods, ideas, and even principles to maintain it.
Even long-standing expertise can rest on uncertain ground if it lacks a deeper, enduring foundation. Therefore, one should be thoughtful: if our efforts are not connected to Krishna, they serve mainly for temporary maintenance and will not stay with us. But when knowledge and effort are connected to Krishna—such as through teachings like the Bhagavad Gita—they become lasting. That kind of learning and realization remains with us, steady and meaningful, beyond changing circumstances.
