Śrīmad-Bhāgavatam · Text 6.1.12
Who is speaking and story frame
नाश्नत: पथ्यमेवान्नं व्याधयोऽभिभवन्ति हि ।
एवं नियमकृद्राजन् शनै: क्षेमाय कल्पते ॥ १२ ॥
nāśnataḥ pathyam evānnaṁ
vyādhayo ’bhibhavanti hi
evaṁ niyamakṛd rājan
śanaiḥ kṣemāya kalpate
My dear King, if a diseased person eats the pure, uncontaminated food prescribed by a physician, he is gradually cured, and the infection of disease can no longer touch him. Similarly, if one follows the regulative principles of knowledge, he gradually progresses toward liberation from material contamination.
