From the viewpoint of Imam Khomeini, although differences are observed in outward aspects, methods, styles and interests and tastes, there is no difference in the meaning and essence of the truth, as truth of any and all affairs is one.
From the Imam's viewpoint, political differences, the discrepancies of philosophers, the disputes of mystics and fuqaha (jurists) are superficial, procedural and personally based on their own taste, not a difference in the truth and meaning.
Therefore, these differences can be called a misunderstanding, which should be removed.
