यदा वै निस्तिष्ठत्यथ श्रद्दधाति नानि-स्तिष्ठञ्छ्रद्दधाति निस्तिष्ठन्नेव श्रद्दधातिनिष्ठा त्वेव विजिज्ञासितव्येति निष्ठांभगवो विजिज्ञास इति ॥ १ ॥
In plain words
When a person is steadfastly dedicated, only then does faith arise; without steadfast dedication, there is no faith. Therefore, it is steadfast dedication itself that we must seek to understand. 'Master, I wish to understand steadfastness.'
Close to the Sanskrit
When indeed one is steadfastly dedicated, then one has faith; one who is not steadfastly dedicated does not have faith; only one who is steadfastly dedicated has faith. 'Steadfastness, indeed, must be desired to be known.' 'O venerable one, I desire to know steadfastness.'
