The three level way is not the path 

Unfortunately, he misunderstood the quotation. He seems to have ignored the statement: “Enlightened human, being disciplined” (sīle patiṭṭhāya naro sapañño). (naro sapañño = the enlightened human). The fact that enlightenment precedes discipline is further supported in the culla vedalla sutta, although it is often misinterpreted even there. In other words, the path is the Supernormal Eightfold Way and not the three levels (sīla, samādhi, and paññā). This means the control of behaviour (sīla) has to be based on an understanding of the reason for control, as indicated by the precedence of the Harmonious Perspective (sammā diṭṭhi). This is why The Supernormal Eightfold Way (Ariya Aṭṭhangika Magga) begins with the Harmonious Perspective (sammā diṭṭhi) followed by the Harmonious orientation (sammā sankappa) before getting into the discipline of behaviour, which is: Harmonious speech (sammā vācā), Harmonious action (sammā kammanta) and Harmonious life (sammā ājīva). This means, this control of behaviour (sīla) is not something to be done on blind faith. If it is done on blind faith, it becomes a heteronomous morality (sīlabbata parāmāsa), which is a morality subject to external impositions. What is needed here is supernormal morality (ariya sīla), which is an autonomous morality based on personal conviction and a quietist and benevolent orientation (aparāmaṭṭha samādhi sanvattanikaη).
