यो यो यां यां तनुं भक्तः श्रद्धयार्चितुमिच्छति।तस्य तस्याचलां श्रद्धां तामेव विदधाम्यहम्॥
yo yo yāṃ yāṃ tanuṃ bhaktaḥ śraddhayārcitum icchatitasya tasyācalāṃ śraddhāṃ tām eva vidadhāmyaham
Word by word
The verse says
Whatever form a devotee wishes to worship with faith, I am the one who makes that very faith steady.
In plain words
He does not correct them.
Someone is praying, with real faith, to what Krishna has just described as a lesser address. His response is to strengthen their faith in it.
Vidadhāmi aham — I myself arrange that.
Where you've felt this · in friendship
You have learned about twenty words of a language and you try them out on the woman who sells you vegetables. She could switch to English and make it easier for both of you. Instead she answers slowly, using only the words she can see you already have. By the end of the month you have forty of them.
Going deeper
Strengthening someone's faith in something you consider partial is an odd move, and it shows what faith is being treated as.
Śraddhā gets translated as faith, but it is closer to the weight a person actually puts on something — what they lean on when it matters. Krishna treats that capacity as more important than its current address. Steadiness first. Accuracy may follow, and the verse does not chase it.
The alternative would be correction, and correction has a poor record. Tell someone their faith is misdirected and you rarely improve their aim. Usually you just remove the leaning and leave nothing in its place.
For anyone who has watched a family member pray in a way they find naive, this is quietly instructive. It does not say they are right. It says the last thing a person needs is to be talked out of the only leaning they have.
