To make the journey easier for those who seek out true happiness, the Spirit André Luiz wrote one of the greatest successes in Spiritist literature in recent years – Green Light. In this moral traffic guide, we can learn to safely apply the brakes in order to move forward smoothly, overcoming roadblocks and avoiding complex accidents that always arise in the paths of those whose consciences hurtle forth without restraint. Received through the psychographic mediumship of Francisco Cândido Xavier, pages of wisdom and elevation unfold for our daily lives, focusing on our behaviour in response to life’s demands. Mindful of the difficulties we encounter, André Luiz – a doctor of souls – doesn’t hesitate to point out the causes of our afflictions, whilst also suggesting appropriate prescriptions for physical and spiritual health.
