For this reason the enlightened person should endeavor only for the minimum necessities of life while in the world of names. He should be intelligently fixed and never endeavor for unwanted things, being competent to perceive practically that all such endeavors are merely hard labor for nothing.
Srimad Bhagavata Purana
श्रीमद्भागवतमहापुराणम्
मूल श्लोकः
अतः कविर्नामसु यावदर्थः स्यादप्रमत्तो व्यवसायबुद्धिः । सिद्धेऽन्यथार्थे न यतेत तत्र परिश्रमं तत्र समीक्षमाणः
ataḥ kavirnāmasu yāvadarthaḥ syādapramatto vyavasāyabuddhiḥ | siddhe'nyathārthe na yateta tatra pariśramaṃ tatra samīkṣamāṇaḥ
