Question: Why does it happen that at a certain stage your beloved teacher does not seem so beloved anymore? Moreover, it seems that he manipulates you and says things that you want to criticize over and over.
Answer: That is natural. A student does not advance without having complaints and criticisms in regard to the teacher. Advancement occurs on two sides: the left and the right, where on one hand you have criticism, and on the other hand, forceful justification.
Therefore, if a critical attitude to the teacher arises in you, it means that you now need to add from the other side, in spite of your opinion, the opinion of others, and in spite of the rejection and even hatred toward the teacher that suddenly might emerge in you. You need to rise above it in faith above reason, to the state where you continue to hold onto him.
It requires tremendous effort from the student. And if you already are in it, congratulations. This work does not end even when you enter the spiritual world at the first spiritual attainment—it continues even on higher degrees.
To the extent that you suddenly feel rejection from your friends in the group, realizing that a completely irrational hatred toward them arises in you, the same irrational hatred and not just a critical attitude will emerge in you toward the teacher. You will need to overcome it through faith above reason.
