The theosophical idea is that the physical man, and all that constitutes his life in the physical world, is but a very partial expression of the self; that in the ego of each there is practically unlimited power and wisdom; that these may be brought through into expression in the physical world as the physical body and its invisible counterparts, which together constitute the complex vehicle of the ego's manifestation, are evolved and adapted to the purpose; and that in exact proportion that conscious effort is given to such self-development will spiritual illumination be achieved and wisdom attained. Thus the light that leads to happiness is kindled from within and the evolutionary journey that all are making may be robbed of its suffering.
