Wikipedia definition:
Masochistic ecstasy refers to the mental and spiritual state, the state of trance in which an individual finds himself. This state can occur during religious meditation, fasting, creative trance, sporting effort, with asceticism (chastity), confinement. Ecstasy is therefore found both in flagellants and in social or erogenous masochists.
Practitioners of are concerned and know, seek out this ecstatic state. In preparation for a session, the dominated engulfs himself in his fantasy world. He meditates on what he will live. He puts himself alone, or with the help of a dominant in a world outside of himself. Almost everyone needs this meditation, a kind of freeze frame before taking action. Some will be content with the trance in which meditation puts them, and they will leave this state without taking the physical act. The state of ecstasy is characterized by confusion which may be surprising to the uninitiated. In the context of a BDSM relationship, some masochists, often women, require special attention. They expect affection and physical protection especially when coming out of the trance.
Endorphins
Pleasure in pain comes, according to specialists, from a surge of endorphins. Endorphin is produced by certain cells of the central nervous system. Endorphins have analgesic properties. In some cases, they make it possible to reduce pain and sometimes to transform it into pleasure. Endorphin would always be, according to specialists, including Dr. Jacques Vigne, a kind of morphine only produced by the body".
According to Dr. Jacques Vigne: "The discovery of endorphins in our body for fifteen years opens new perspectives on the mind-body link, with indirect consequences on the understanding of the mode of action and meditation. "These are peptides, i.e. short chains of amino acids; they are called "opioids" because they have an action similar to that of opium and morphine. ยป
A study by Dr. Levine at the University of California can be indirectly related to meditation: Levine showed that endorphins mediate the placebo effect, that is, patients who suppress their own pain believing they have received an effective drug do this through endorphins. ยป
Dr. Vigne writes "that it is not absurd to speak of a link between meditation and endorphins.
"During childbirth, women who exercised during pregnancy produce more endorphins than others."
The ecstatic state is very clear after the birth of the child which is called deliverance: net cessation of pain and rise of endorphins.
Endorphins have "narcotic" properties. As the word amazement comes back into the vocabulary of mystics in common with mental arrest.
