I read two books, one by the lady who is in the caption image of the video and another by a male disciples. Interestingly there is nothing about kundalini yoga and psyche research in their experiences.

This means that kundalini yoga practice may not result in self realization, no matter who teaches or does it.

But as for the responsibility of the mishaps, sure the spiritual master has fault in it. Why the question?

Better if one learns from his mistakes.

Here are the two books of interest / warning / do not expect details about kundalini yoga breath infusion and samyama meditation.
