Srimad Bhagavatam Canto 10, Chapter 40, Text 10

SB 10.40.10

yathadri-prabhava nadyah
 parjanyapuritah prabho
visanti sarvatah sindhum
 tadvat tvam gatayo ’ntatah
 
Translation: 
 
As rivers born from the mountains and filled by the rain flow from all sides into the sea, so do all these paths in the end reach You, O master.
 
Purport: 
 
Lord Krsna Himself speaks on this issue of worship in the Bhagavad-gita (9.23-25):
 
ye ’py anya-devata-bhakta
 yajante sraddhayanvitah
te ’pi mam eva kaunteya
 yayanty avidhi-purvakam
 
aham hi sarva-yajñanam
 bhokta ca prabhur eva ca
na tu mam abhijananti
 tattvenatas cyavanti te
 
yanti deva-vrata devan
 pitrn yanti pitr-vratah
bhutani yanti bhutejya
 yanti mad-yajino ’pi mam
 
“Those who are devotees of other gods and who worship them with faith actually worship only Me, O son of Kunti, but they do so in a wrong way. I am the only enjoyer and master of all sacrifices. Therefore, those who do not recognize My true transcendental nature fall down. Those who worship the demigods will take birth among the demigods; those who worship the ancestors go to the ancestors; those who worship ghosts and spirits will take birth among such beings; and those who worship Me will live with Me.”
