The pineal gland is a conical organ located in the middle of the brain, near the brainstem. This gland is responsible for secreting melatonin and regulating the circadian rhythm, but there is more to it than that. It also produces dimethyltriptamine (DMT), which is associated with transcendental states and near death experiences. It has long been considered to be the third eye within human beings, a pathway to an inner dimension. The Lucia No.3 shines through the pupil of the eye and penetrates the pineal gland and causes secretions of endogenous (internally-produced) DMT, activating intensely beautiful colorscapes and symbology accessed in the subconscious mind.
