When I was trying to think of an equivalent for the word "misconception" in sanskrit, some of the words that came up were
- अयथार्थः - loosely translated as 'false'
- विपर्यय - reversed, inverted, opposite hence erroneous knowledge
- तर्कः - this is very specific to तर्कशास्त्र - hypothetical reasoning/confutation
- मूढग्राह - this term I came upon at a website. I liked it immediately.
Sri Rama Shastri was very famous for thinking and providing out of the box explanations for some simple stuff. He has given a wonderful twist to this expression.
"ब्राह्मणाः भो! जनप्रियाः"
A brahmin's work, as enumerated by Manu, was यजनं, याजनम्, अध्ययनम्, अध्यापनं, दानं, प्रतिग्रहः, च। Each one of these was designed with the welfare of the whole world in mind. A brahmin performed sacrifices for लोकक्षेम, he helped others to perform sacrifice. He studied in order to teach others. He accepted donation in order give more in charity.
अत एव, भोः जनाः, जनप्रियान् ब्राह्मणान् भोजनप्रिया इति मूढबुद्धिं त्यजन्तु।
