The ideas of yoga, sahaja, self-realization and meditation orbit around another central theme in the spiritual culture of the East which, simply put, relates to the idea that one’s perception of true reality is obscured by one’s own mental complexities (preconceptions, emotions, opinion and intellect). Meditation represents the opposite condition to mental complexity because its essential element is the experience of a trans-mind state.
