sa taya shraddhaya yuktastasyaradhanamihate labhate ca tatah kamanmayaiva vihitanhi tan7.22
Meaning
Endowed with that faith, the devotee worships that form of deity and obtains their desires. But in reality, those benefits are granted by Krishna alone.
वह उस श्रद्धा से युक्त होकर उस देवता का पूजन करता है और उससे मेरे द्वारा विधान किये हुए इच्छित भोगों को निःसन्देह प्राप्त करता है।
This is verse 22 of 30 in Chapter 7 (Jnana Vijnana Yoga) of the Bhagavad Gita.
