Discourses on morality made with the help of an intelligent understanding of the true letter and spirit of the scriptures, should be lauded and not those which are made with the help of anything else. Sensible words, even if heard from an ignorant person, are regarded as pious and wise.
आगतागमया बुद्ध्या वचनेन प्रशस्यते। अज्ञानाज्ज्ञानहेतुत्वाद् वचनं साधु मन्यते॥
