Every path and every master works backward to what seems to be the salient thing about their own Awakening, because a teacher can only teach what s/he knows. Byron Katie is about dropping the Story. Eckhart Tolle is about being Present. Gautama Buddha is about being Present and inwardly silent. The Sufis are about losing oneself in the inner Divine Beloved … and they have developed methods of inducing those experiences in others in hopes that seekers will make that leap from spiritual experience to spiritual knowledge.
All these methods and the experiences they induce are based in Truth but aren’t Truth; all work for some people and none work for everyone. Many become very adept at certain states and can be very fine teachers of attunement but don’t actually Awaken. The Masters understand a certain futility in it all, because Awakening is un-caused and only comes through Grace, but they are moved by a deep love & compassion to teach these methods anyway.
