Stanislav Grof says
Authentic spiritual systems are based on ... systematic exploration of the psyche using well-defined mind-altering technologies. They are results of a process that in many ways resembles the scientific method.
Authentic spirituality makes a difference, not within the extended time frames of Old World Spirituality(i.e. years, decades, and lifetimes), but within short, workable, and verifiable time frames of days, weeks, and months. In other words, techniques and principles provided by an authentic spirituality will have immediate and discernible positive impact.
