Sūta said: The slow (manda)[8] consists of twelve moments which form one stroke or blow (udghāta). The middling consists of two strokes. The superior has three strokes, i.e. thirty moments. The three respectively generate sweating, shivering and rising up. When the following symptoms are seen the prāṇāyāma[9] is excellent, for it denotes the onset of bliss. The symptoms are: reeling due to drowsiness, horripilation, sensation of hearing some sound, pressing of one’s own limbs, shivering, vertigo born of sweating, fixation, absence of knowledge and unconsciousness.
