Instead of seeking Crystal panaceas or drugs and medications to constantly modulate our state, Kyle Russell suggests going deeper, to do the spiritual work necessary to uncover the underlying dynamics of our state - without discounting the value of a new attitude, dietary changes, or needed medical interventions - which of course have their own limitations.
Russell discusses five stones for healing to illustrate the multiple factors can be at work and/or helpful in impacting our situations. He does not make pseudo-Scientific claims or profess reliance on some ancient Native traditions. Karma is one of many (mostly unseen) factors impacting our lives, and bad things (unfortunately) happen to good people. Your destiny is not entirely in your control.
