An icebreaker
An emergency medicine physician wrote a widely read book arguing that Buddhist awakening is a concrete, attainable goal that can be mapped like any other skill, not a rare, mystical exception. He also writes candidly about the difficult, destabilizing stretches serious practice can produce.
In his chapter on the Dark Night, he described facing surfacing emotional material and a crisis of identity at once as especially difficult and sometimes overwhelming, and urged steady practice and inquiry rather than escalation through it.
Directing a research lab at Brown University, she has documented a range of difficult and destabilizing experiences tied to intensive meditation, and founded an organization providing support and clinician training for people going through them.
Teaching an approach closely associated with Ingram's, he has likewise argued that classical meditative attainments can be pursued directly and tracked concretely, treating them as trainable milestones rather than rare, unexplainable events.
