✦ Meaning
This sharp and widely quoted verse from Chanakya Niti pairs two useless possessions: knowledge that stays locked in books and wealth that lies in someone else's hands. When a real need arises, neither comes to one's aid. It is a powerful lesson that learning must be internalised through practice and resources kept within one's own command.
Origin & Story
Chanakya Niti · Chanakya (Vishnugupta / Kautilya) · Ancient India (c. 4th–3rd century BCE)
Chanakya, himself a great teacher, insisted that knowledge has value only when it is mastered and ready for use. In this verse he likens bookish, unpractised learning to wealth deposited in another's hands: both look like assets, but neither answers the call when the hour of action comes — a pointed reminder that true vidya lives within the learner.
✦ As told in scripture
Teachers cite this verse to spur idle students, telling how many a scholar found their shelves of books worthless in a crisis while one who had truly absorbed even a little knowledge met the moment with ease — proof that only the learning one carries within can be summoned at need.

पुस्तकस्था तु या विद्या परहस्तगतं धनम्। कार्यकाले समुत्पन्ने न सा विद्या न तद्धनम्॥
pustakasthā tu yā vidyā para-hasta-gataṁ dhanam। kārya-kāle samutpanne na sā vidyā na tad dhanam॥
Meaning:Knowledge that remains only in books and wealth that has passed into another's hands — when the time of actual need arises, that knowledge is of no use, and neither is that wealth. Chanakya warns that learning must be mastered within oneself and wealth kept within reach, for only what one truly commands will serve one in the hour of need.
