In the Buddhist's deeper meditational training--minutely described in the Abhidhamma collected and recorded by the Buddha's disciples--it is noteworthy that ecstasies first, and bliss next, cease about halfway along the path, to be succeeded by intense inner quiet for the advanced and terminal stages. Yet the texts on yoga which go beyond this halfway stage are few, and are studied by few. For it is at this point that mysticism ends, and real philosophy begins.
