"Sikhism lays more emphasis on dynamism, non-dualism and social involvement. All these characteristics of the spiritual Reality imply that Sikhism puts forth a dynamic metaphysical system. In this dynamic concrete system the differences or modifications are not negated. There is another way to explain the nature of non-dual Reality in terms of them personal and personal unities."
