Bhagwad Gita
Chapter 7, Verse 23
अन्तवत्तु फलं तेषां तद्भवत्यल्पमेधसाम्।
देवान्देवयजो यान्ति मद्भक्ता यान्ति मामपि।।7.23।।
Men of small intelligence worship the demigods, and their fruits are limited and temporary. Those who worship the demigods go to the planets of the demigods, but My devotees ultimately reach My supreme planet.
