Attitude to have when explaining something ..

In accordance with the divine teachings in this glorious dispensation we should not belittle anyone and call him ignorant, saying: 'You know not, but I know’. Rather, we should look upon others with respect, and when attempting to explain and demonstrate, we should speak as if we are investigating the truth, saying: 'Here these things are before us. Let us investigate to determine where and in what form the truth can be found.’ (Abdu’l-Baha, Selections from the Writings of ‘Abdu’l-Baha, p. 30)
