Bhagavad Gita Chapter 9, Verse 25

यान्ति देवव्रता देवान्पितॄन्यान्ति पितृव्रताः | भूतानि यान्ति भूतेज्या यान्ति मद्याजिनोऽपि माम् ||

yānti deva-vratā devān pitṝn yānti pitṛ-vratāḥ bhūtāni yānti bhūtejyā yānti mad-yājino 'pi mām

Those who worship the gods go to the gods; those who worship the ancestors go to the ancestors; those who worship spirits go to the spirits; but those who worship Me come to Me.

Krishna reveals the law of destination: 'Yānti deva-vratā devān'—those devoted to gods (deva-vratāḥ) go (yānti) to the gods (devān). 'Pitṝn yānti pitṛ-vratāḥ'—those devoted to ancestors (pitṛ-vratāḥ) go (yānti) to the ancestors (pitṝn). 'Bhūtāni yānti bhūtejyāḥ'—those who worship spirits (bhūtejyāḥ) go (yānti) to spirits (bhūtāni). 'Yānti mad-yājino 'pi mām'—those who worship Me (mad-yājinaḥ) also (api) come (yānti) to Me (mām). This is the law of destination: you go where you worship. If you worship gods, you go to gods. If you worship ancestors, you go to ancestors. If you worship spirits, you go to spirits. But if you worship the Supreme, you come to the Supreme. This reveals the supremacy of devotion to the Supreme: all other worship leads to temporary destinations, but devotion to the Supreme leads to the Supreme—eternal liberation. This is why devotion to the Supreme is superior: it leads to the Supreme, not to temporary destinations.
