Present day neurophysiology stops with attributing thinking processes as the highest level of function of the brain. It has been common knowledge to oriental thinkers for many centuries, that there are many further states of the human mind, culminating in the state of thoughtless awareness; the fourth state of consciousness. This state must have a physiological basis. The complicated structure of the brain, the extravagant abundance of neural and glial elements in the brain, the infinite possibilities of synaptic junctions and synaptic transmission, and the multitude of neurotransmitters and neuromodulators; all these point to the definite possibility of a much greater level of performance and achievement for the human brain than has been apparent so far. Not only the theories but also the experience of Eastern seers have shown that the brain can transcend the boundaries of logic and reason, and experience states of awareness, commonly unrecognized. In the past few decades, knowledge about the functioning of the human brain has been growing exponentially and scientists of diverse disciplines are concentrating on unraveling its mysteries. It is necessary for scientists to investigate this state with all available tools and find the neurophysiological basis of this state.
当今神经生理学将思维过程视为大脑的最高功能水平。几个世纪以来，东方思想家就已经知道，人类意识还有许多其他状态，最终达到无思觉知的状态，即第四种意识状态。这种状态必定有其生理基础。大脑的复杂结构、大脑中神经和胶质细胞成分的丰富多样、突触连接和突触传递的无限可能性，以及众多的神经递质和神经调质；所有这些都表明，人类大脑具有比迄今为止所显现的更高水平的功能和成就的明确可能性。不仅理论，而且东方先哲的经验都表明，大脑可以超越逻辑和理性的界限，体验到通常未被认可的意识状态。在过去几十年里，关于人类大脑功能的知识呈指数级增长，不同学科的科学家都在专注于揭开其奥秘。科学家有必要用所有可用的工具来研究这种状态，并找到这种状态的神经生理基础。
