June Gītā: 7.21

Yo yo yām yām tanun bhaktah
Śraddayā ‘rcitum icchati 
Tasya tasy ‘ācalām śraddhām
Tām Eva vidadhāmy aham

’In whatever you find faith in I (Krishna) will steady that faith.’
Bhagavad Gītā 7.21

You find this famous quote from the Bhagavad Gita on posters in many cafes and shops in India. Partly because it’s easy to quote. Its meaning is simple and direct. 

One may think that to follow the Gita you have to be a Krishna devotee. But here Krishna is saying it is your faith, your path, your practice. As long as you do that with devotion it will become stronger.
