Moksa Opadesa Yoga: Bhagavad Gita Chapter 18 [Final Revelations of the Ultimate Truth]
Krishna Said > Shaloka: 8
Anyone who gives up prescribed duties as troublesome, or out of fear, is said to be in the mode of passion. Such action never leads to the elevation of renunciation.
One who is in Krishna consciousness should not give up earning money out of fear that he is performing fruitive activities. If by working one can engage his money in Krishna consciousness, or if by rising early in the morning one can advance his transcendental Krishna consciousness, one should not desist out of fear or because such activities are considered troublesome. Such renunciation is in the mode of passion. The result of passionate work is always miserable. Even if a person renounces work in that spirit, he never gets the result of renunciation.
