Written in 1960, Andrea's last major work gives an unsurpassed account of the highest altitudes of the mystic way, the universal path of spiritual enlightenment. The spiritual realm of Shamballa, as Andrea defines, is beyond even many of the masters. And yet, it must eventually be striven for by all who seek the holy existence of union with God. Through nearness to Shamball, the humble soul overcomes the Nemesis of Karma and draws upon Shamballic sources of infinite creative power to accomplish a remarkable transformation. The author considers the life of the advanced student who has passed through a hidden portal to a secret inner life of instruction, far from the comforts of the armchair mystic. The living experience of such a person is replete with trials and tribulations that serve as catalysts for ever greater advancement and achievement. Mental creation through visualisation and the application of will is a crucial part of the "technique" and when applied correctly with diligence, an inner alchemy is begun as the student increasingly comes under the numinous influence of Shamballa. The student's life from that moment on is redirected wholly and exclusively in accordance with the Master's intent, and a crucial transformation will have begun. It is from then on up to the disciple to do all that is possible to keep up with a new and demanding pace of change.
