वृत्तयस्त्वहं-वृत्तिमाश्रिताः ।वृत्तयो मनो विद्ध्यहं मनः ॥
वृत्तयः तु अहंवृत्तिम् आश्रिताः वृत्तयः मनः विद्धि अहम् मनः
In plain words
There are no thoughts and then a mind holding them. The thoughts are the mind. And they are all leaning on one of their number: the one that says 'I'. So when you say 'my mind', you are pointing at that single thought wearing the others as clothes.
Word for word
But thoughts rest on the 'I'-thought. Thoughts are the mind; know that the 'I' is the mind.
