विष्णुपुराण - सा विद्या या विमुक्तये

तत्कर्म यन्न बंधाय सा विद्या या विमुक्तये ।
आयासायापरं कर्म विद्यान्न शिल्पनैपुणम् ॥

- विष्णुपुराण

That which does not create attachments is a good action. All other actions only drain your energy. Only the education that liberates is the right kind. All other education is like sculpturing.
