When by discrimination and right action man “roasts” all the seeds of evil tendencies stored in the mind, each microscopic brain cell becomes a throne for a brilliant king of wisdom, inspiration, and health, who sings and preaches the glory of God to the intelligent body cells. Men who have attained this state are really free. Such liberated beings are untouched by karma in future incarnations, and reincarnate only in order to wipe away the tears of the karma-bound. These liberated masters are haloed in invisible healing light. Wherever they go, they scatter the light of prosperity and health.
