Baha'is themselves are commanded by Baha'u'llah to investigate truth independently, to "see with" their "own ·eyes, and not through the eyes of others". Every Baha'i is at liberty, nay is urged, to freely express his opinion and his understanding of the Teachings, but all this is in a totally different category from that of a Baha'i who opposes the clear Teachings of Baha'u'llah.
