Acquisition of truth, not qualifications, is what matters. Others who know some of what is going on should be sought out and tested.
"Do not believe in anything simply because you have heard it. Do not believe in anything simply because it is spoken and rumored by many. Do not believe in anything simply because it is found written in your religious books. Do not believe in anything merely on the authority of your teachers and elders. Do not believe in traditions because they have been handed down for many generations. But after observation and analysis, when you find that anything agrees with reason and is conducive to the good and benefit of one and all, then accept it and live up to it.”
Siddhārtha Gautama Buddha
There are said to be 80,000 paths to enlightenment. None involves accepting what you are told by any other human being or a book. Much yogic teaching is available in book form and should be weighed by the open mind method. Highly critical thinking is the only true guide to wisdom. There is a cost as friendships will wither.
Temptation increases as wisdom increases. Social life is desirable even among monks.
