C. W. Leadbeater 
A Textbook Of Theosophy 

Theosophy is not only a basis of religion; it is also a philosophy of life. As such, its main teachings are reincarnation and the law of Karma. Karma is the outcome of the collective life, a law of ethical causation. In the past incarnation the ego had acquired certain faculties, set in motion certain causes. The effect of these causes and of causes set in motion in previous incarnations and not yet exhausted are its Karma and determine the conditions into which the ego is reborn. Thus inequalities of natural gifts, e.g. genius, of temperament and of character are explained. The law of progress is the law of involution and evolution, the returning of the Divine Spark into a unity with Spirit through various reincarnations, which are viewed as a process of purification. Sin, poverty, and misery are the fruits of ignorance, and are gradually removed as the spirit in us becomes freed from earthly dross. There is no heaven nor Hell. Death is the passage from this state of life to another. There is an evolution behind and before, with absolute certainty of final attainment for every human soul, i.e. to be one with the Absolute. As man advances in this process his spirit becomes stronger, and can develop latent powers, not shown in ordinary mortals.
