Without any doubt...

Without any doubt, if we do not control our instincts, and they dominate over us, even our knowledge and intellect will be imprisoned, and the human being, like the oppressors of history, will be changed into wolves which are far more dangerous than the wolf of the wilderness. We need a teacher to learn ethics. We need a model so that we can learn from him according to the principle whereby one narrates something and others follow.

A perfect and disciplined human being, from every point of view, is required to take our hand upon this way, which is full of twists and turns, and prevent the rebellion of our instincts, to have virtuous .principles and his deeds and words sit upon our hearts and very beings, nurture courage, bravery, friendship with other human beings, brotherhood, forgiveness, loyalty, correctness, trustworthiness and purity within our spirits.
