I once heard an interesting phrase from a friend: the day people stopped consulting a rabbi, they started going to a psychologist.
The idea sounds interesting, but to understand it, we must first understand what a rabbi is.
It is generally explained that the Hebrew word "rabbi" is composed of the first letters of the words "rosh," "bnei," and "israel," meaning "The head of the Jewish people." A rabbi is like the head in relation to the body, from which all the body's vitality originates and which guides it. However, this concept is applied specifically to a Rebbe, a true leader from whom we all learn a path in the service of God.
On the other hand, a rabbi is someone who knows the laws of the Torah and their practical application in our times. Furthermore (and depending on the type of rabbi, their school of thought, etc.), the rabbi may understand how the Jewish soul functions, its relationship with God, the purpose and meaning of life, and so on—questions many people ask themselves and for which they seek answers in the most unlikely places, such as Buddhism, sports, friends, or even drugs.
In other words, a rabbi understands what is called daat Torah - the opinion of the Torah - on the various matters of daily life.
People think the Torah is a book of stories, or an outdated code of laws (in fact, the other day I saw a book in a bookstore about "New Judaism"—God forbid! God doesn't change, His will and wisdom don't change, therefore His Judaism is immutable...). The Torah is a guide for life for all generations, in every place we may ever find ourselves. And the rabbi is like the tool to access his opinion and perspective (that of the Torah, and therefore, God's) on the conflicts in each person's life.
Because the Torah is the heritage of the entire Jewish people. It belongs to everyone, and everyone is intrinsically connected to it. It's simply a matter of opening your eyes, opening your mind, and daring to explore your inner self to grasp the very reason for your life.
To conclude, the other day a doctor asked me when was the last time we had blood tests, urine tests, etc., done on one of my children... it's obvious that, from time to time, one should "get checked" to see how everything is... the same goes for the rabbi, but on a spiritual level: when was the last time he spoke to you?
