नोत्पद्यते विना ज्ञानं विचारेणान्यसाधनैः ।यथा पदार्थभानं हि प्रकाशेन विना क्वचित् ॥ ११ ॥
In plain words
Knowledge does not arise without inquiry — no other method will produce it. Just as nothing, anywhere, ever becomes visible without light.
Close to the Sanskrit
Knowledge does not arise without inquiry, by other means; just as the appearing of an object does not, indeed, ever occur without light.
