By the 1848 Adi Brahma Dharma published doctrine of Debendranath Tagore, it was held that present Hinduism doctrine is corrupted, but that the original Vedas of pre-Aryan times (being relatively pure, though still fallible and not Scripture to be relied on) as reflected by 11 judiciously chosen Upanishads also speak of a single formless God who requires no temple or priest or idol for worship, only a rational and pure conscience of an intelligent mind. That there is no caste - high or low - all people are equal, in this World and before God. The doctrine of reincarnation is rejected. The doctrine of God being incarnate is also rejected.
