महाभारत - शान्ति - जीर्णमायुः

इदं लब्धमिदं नष्टमिदं लप्स्ये पुनर्धिया ।
इति चिंतयतामेव जीर्णमायुः शरीरिणाम् ॥

- महाभारत, शान्ति

idam labdham idam naShTam idam lapsye punaH dhiyA ।
iti chintayatAm eva jIrNam AyuH sharIriNAm ॥

Got this, lost that, will think about how to regain that later - people spend their entire lives in such thoughts.
