na labhyate yad bhramatām upary adhaḥ
tal labhyate duḥkhavad anyataḥ sukhaṁ
kālena sarvatra gabhīra-raṁhasā
Persons who are actually intelligent and philosophically inclined should endeavor only for that purposeful end which is not obtainable even by wandering from the topmost planet [Brahmaloka] down to the lowest planet [Pātāla]. As far as happiness derived from sense enjoyment is concerned, it can be obtained automatically in course of time, just as in course of time we obtain miseries even though we do not desire them.
