The general idea in the popular and religious circles of India is that the highest state of illumination is attained during a trance condition (samadhi). This is not the teaching in the highest philosophic circles of India. There is another condition, sahaja samadhi, which is described in a few little-known texts and which is regarded as superior. It is esteemed because no trance is necessary and because it is a continuous state. The inferior state is one which is intermittently entered and left: it cannot be retained without returning to trance. The philosophic "fourth state," by contrast, remains unbroken even when active and awake in the busy world.
