अज्ञः सुखमाराध्यः सुखतरमाराध्यते विशेषज्ञः ।
ज्ञानलव दुर्विदग्धं ब्रह्माऽपि नरं न रञ्जयति ॥

Meaning:
To convince an ignorant person is easy. It is even easier to convince a learned person

. But even Lord Brahma cannot explain and convince a person who has limited knowledge but thinks high of himself.
