Abstract
Understanding the true nature of an individual, be it a child or an adult, a male or a female, is almost an impossible task. The vast abyss like behaviour of a human mind is virtually unfathomable. Yet, with the advent of neurosciences, it can be said that we, as the medical fraternity, have been in a position to decipher a considerable part of the human mind. This review accepts the fact that religion and theology have extreme reverence and respect. Yet, when it comes to extraordinary beliefs, phenomena, unimaginable feats and emotional deviations of the human mind, especially those which involve deep faiths and beliefs, comprehensive neuroscientific explanations from the emerging data, with the aid of elaborate neuroimaging, have proved to be extremely rational and logical. This review did make an attempt to untangle some facets of spirituality and to make rational explanations of the same. It was an attempt to understand the function of the mind (as an abstract) and the brain, on the spiritual experiences and sudden enlightments, the experience of togetherness with the universe, and to understand the phenomena of trance and an altered state of consciousness, which is better referred as the emerging science of neurotheology.
