Leo Tolstoy's The Kingdom of God is Within You provides an extended discussion of the difference between an authentic understanding of Christ's teachings, and an unaligned, hypocritical, an inauthentic reading used to justify the status quo, rather than emancipate humanity, as Christ had intended.

In other words, techniques and principles provided by an authentic spirituality will have an immediate and discernible positive impact.
