The point is to have someone lay before you their experiences and to teach the particular praxis of a Tradition. The spiritual rabbit hole can go very deep alone, but with the momentum gained from working with a teacher and group, the bottom of that hole drops even deeper. This truth is something that cannot be explained in full to someone that has never experienced the shift in energy from working solo to working with guidance.
In the BTW and TIW communities, there is a proverb used. Let there be no doubt that this proverb originates in Buddhism,
Be wary and be discriminate when approaching someone as a teacher. Likewise, don’t settle on just anyone, just because they are the only local person found. Verify that your prospective teacher is trained themselves and vouched for. A vouch means two things, which is often only thought of as only meaning one. It means, that someone has the lineage claimed, and that the person vouching (make sure the vouch comes from a reliable source) is giving their word that the person is reputable. On rare occasion I have been asked for a vouch, but the best I could do was say, “Yes, they have that lineage.” I was not able to, in good conscious, to give a vouch for their being a reputable teacher. Remember, it is the job of the teacher to bring you to their level, and nothing else.
A good teacher strives to help you down the path, not to walk it for you.
Just as a teacher will not appear until ready, sometimes they appear when not expected. Recognize when this happens and embrace it or the opportunity will pass by. Cease the moment and allow the experience to broaden the spiritual horizons.
