Srimad Bhagavatam Canto 10, Chapter 40, Text 07

SB 10.40.7

anye ca samskrtatmano
 vidhinabhihitena te
yajanti tvan-mayas tvam vai
 bahu-murty-eka-murtikam
 
Translation: 
 
And yet others — those whose intelligence is pure — follow the injunctions of Vaisnava scriptures promulgated by You. Absorbing their minds in thought of You, they worship You as the one Supreme Lord manifesting in multiple forms.
 
Purport: 
 
The word samskrtatmanah, “they whose intelligence is pure,” is significant here. It implies that the worshipers mentioned before have not completely purified their intelligence of material contamination and thus worship the Lord indirectly. Those who are purified, however, directly worship the Lord, either as the Supreme Personality of Godhead, Lord Krsna, or as one of His various plenary forms, such as Vasudeva, Sankarsana, Pradyumna or Aniruddha, as indicated here.
