Man explains things in two ways. One explanation originates from his personal feelings, thoughts and understanding. This cannot stand as proof or criterion for all and does not satisfy the hearts. The other is a statement supported by proofs. It produces significant results and promulgates momentous matters which are necessary to the world of man. It is like the explanations and proofs of the Bahá'ís, who invite all to the oneness of humanity and to universal peace. This explanation has proofs and is effective.
