Swami Abhedananda

"Hinduism stands like a huge banian tree spreading its far reaching branches over hundreds of sects, creed and denomination and covering with innumerable leaves, all forms of worship, the dualistic, the qualified non-dualistic and monistic worship of the one Supreme God, the worship, of the Incarnation of God and also hero worship, saint worship, ancestor worship and the worship of the departed spirit. It is based on the grand idea of universal receptivity. It receives everything."

"The doctrine of Reincarnation differs from the accepted theory of Evolution in admitting a gradual but continuous evolution of the subtle body through many gross forms. The gross body may appear or disappear, but the subtle body continues to exist even after the dissolution of the gross body and re-manifests itself in some other form...The theory of Reincarnation when properly understood will appear as a supplement to the theory of Evolution. Without this most important supplement the Evolution theory will never be complete and perfect. Evolution explains the process of life, while Reincarnation explains the purpose of life. Therefore, both must go hand in hand to make the explanation satisfactory in every respect."

"Evolution of the body depends upon the evolution of the germ of life or the individual soul. When these two are combined the explanation becomes perfect. The theory of Reincarnation is a logical necessity for the completion of the theory of Evolution. If we admit a continuous evolution of a unit of the germ of life through many gross manifestations then we unconsciously accept the teachings of the doctrine of Reincarnation. In passing through different forms and manifestations the unit of life does not lose its identity or individuality. As an atom does not lose its identity or individuality (if you allow me to suppose an atom has a kind of individuality) although it passes from the mineral, through the vegetable, into the animal, so the germ of life always preserves its identity or individuality although it passes through the different stages of evolution."
