I understand the biggest mistake an aspirant often makes is to falsely identify lower Samadhi with higher or the highest Samadhi; but, how can a man who makes such a mistake guard himself against it?

When one rises to the state of Samadhi, he does not make the mistake of doubting as to
whether it is lower or higher or the highest. He knows what it is without doubt, quite naturally.
