Endeavors merely for sense gratification or material happiness through economic development are not to be performed, for they result only in a loss of time and energy, with no actual profit. If one’s endeavors are directed toward Kṛṣṇa consciousness, one can surely attain the spiritual platform of self-realization. There is no such benefit from engaging oneself in economic development.
Srimad Bhagavata Purana
श्रीमद्भागवतमहापुराणम्
मूल श्लोकः
तत्प्रयासो न कर्तव्यो यत आयुर्व्ययः परम् । न तथा विन्दते क्षेमं मुकुन्दचरणाम्बुजम्
tatprayāso na kartavyo yata āyurvyayaḥ param | na tathā vindate kṣemaṃ mukundacaraṇāmbujam
