The investigation of truth, the slogan of Baha’ism

Bahaismiran:

In a trip to Europe and America expended by Baha’is, Abdul Baha encountered the new cultures and thoughts benefited for the Baha’is community as the twelve principles.

The most important issue exploited by the Baha’is to proselytize their creed is the twelve principles. Posing these principles, the Baha’is want to say that the Baha’ism is a modern faith and to consider themselves as superior ones in international associations. They claim that they can govern and control the world through these teachings. One of these twelve principles is the investigation of truth. It should be noted that they not only don’t obey and act those orders; but also, act against them. For instance: Bahaullah says in the book “The prayers of the beloved Excellency”:

“Become blind in order to see my charm and become deaf to hear my tenor and voice; be ignorant to exploit my knowledge and become poor to profit by my eternal wealth sea. Be blind means not to see anything and anyone except my charm; be deaf means not to hear any speech except for mine; become ignorant means not to learn except for my knowledge.”

Now, it should be asked: How can a person who is blind, deaf and ignorant investigate the truth? Have the Baha’is thought yet that how a person who is blind, deaf and ignorant can investigate the truth?
