Kabbalah has historically limited study of foundational texts such as the Bahir to students judged ready for it, and this widely published translation's own pages do not say whether that limitation reaches this edition or a citation drawn from it.
What would resolve this Someone familiar with how this translation is actually used in practice today confirming whether it is treated as open study material or as a text still reserved for prepared students.
