Do not consider the speaker; rather consider his( her )utterance.
But its full observance is not possible for anybody, becauseever ybody assumes the speech as the product of speaker's being. In view of material tools, speech is the same transformation inman's energies. Chemical energy is transformed into mechanic alenergy in the cells and mechanical energy to acoustic energy.
And in view of spiritual contents and materials, it is theproduct of thoughts, education, environment, knowledge, attributes, and spiritual states.
Thus, any speech has the same color of its speaker, andcarries the speaker's attributes, either his spirituality or his uglyand bad attributes, and on this account, when an utterance isissued by a virtuous individual, all windows of human spirit areopened to it, and all existence of man receives it.
And in contrast, a speech uttered by an impure and evilperson faces with the unconscious negative reaction of thehearer, and the windows of his spirit are closed to it.
