Nazir - Ideal?

Parashat Naso includes the details of the laws surrounding one who decides to become a nazir. A nazir is one who makes extreme decisions in his life, and there is a debate among the sages  regarding the  proper attitude toward the nazir– is nazir doing something praiseworthy or not?

We explore the Ramban's perspective to gain insights about  moderation as a general ideal, but extremes being sometimes necessary to counter sinful instincts - ideas that can be applied to the nazir. The great man is the man who understands his failings and works to overcome them, which is what the nazir may be doing. As human beings, we need to know our weaknesses and strengths, work with our weaknesses, and make the right decisions despite them.
