। ॥ २१० ॥
In plain words
When your understanding comes to rest in what the guru says and what Vedānta says, settled, with no doubt left in it — 'this is true' — that is śraddhā. That is the root cause from which liberation is reached.
Close to the Sanskrit
That intellect which, regarding the statements of the guru and of Vedānta, is of the very nature of certainty — 'this is true' — that indeed is śraddhā, the root cause for the attainment of liberation.
