Who Is a Kabbalist?
The depths of the Creator’s secrets cannot be understood by the human mind [because it thinks egoistically], but only in accordance with Kabbalah [by correcting oneself from egoism to bestowal], learned from great people [teachers] whose hearts have been penetrated [filled] with the Creator’s Light [and who can therefore teach others how to attain it].
– Rav Kook, Orot Kodesh, 1, 101
Only the true righteous [those who have attained the Creator’s quality of bestowal, justify Him, and are therefore called righteous] are capable of understanding [attaining in the quality of bestowal, the Light of Hassadim] the purpose of the world to come [the Light of knowledge, the Light of Hochma].
– Rabbi Nahman of Breslav, Likutey Moaran, Talk 18
