Laughter is a loud laugh, Aha, Aha, by dilatation of the throat and lips. Song is a celebration of the qualities, glories, &c., of Maheśvara, according to the conventions of the Gandharva-śástra, or art of music. The dance also is to be employed according to the _ars saltatoria_, accompanied with gesticulations with hands and feet, and with motions of the limbs, and with outward indications of internal sentiment. The ejaculation _hum_ is a sacred utterance, like the bellowing of a bull, accomplished by a contact of the tongue with the palate, an imitation of the sound _hudung_, ascribed to a bull, like the exclamation Vashat. Where the uninitiated are, all this should be gone through in secret. Other details are too familiar to require exposition. The postures are snoring, trembling, limping, wooing, acting absurdly, talking nonsensically. Snoring is showing all the signs of being asleep while really awake. Trembling is a convulsive movement of the joints as if under an attack of rheumatism. Limping is walking as if the legs were disabled. Wooing is simulating the gestures of an _innamorato_ on seeing a young and pretty woman. Acting absurdly is doing acts which every one dislikes, as if bereft of all sense of what should and what should not be done. Talking nonsensically is the utterance of words which contradict each other, or which have no meaning, and the like. The subsidiary religious exercise is purificatory subsequent ablution for putting an end to the sense of unfitness from begging, living on broken food, &c. Thus it is said by the author of the aphorisms: Bearing the marks of purity by after-bathing.
