The Dionysian Mysteries were a ritual which used intoxicants and other trance inducing techniques, such as dance and music, to remove inhibitions and artificial societal constraints, liberating the individual to return to a more natural and primal state. It also afforded a degree of liberation for the marginals of Greek society: women, slaves and foreigners.
In their final phase the Mysteries apparently shifted from a chthonic, primeval orientation to a transcendental, mystical one, with Dionysus altering his nature accordingly (much in the same way as happened in the cult of Shiva). Some see these Mysteries, with their resurrected god and secret knowledge about the afterlife, as the precursor of the Eleusinian Mysteries, Orphic Mysteries, Gnosticism and Early Christianity.
By its nature of a mystery religion reserved for the initiated, most aspects of the Dionysian cult remain unknown and were lost with the Decline of Hellenistic polytheism. Our current knowledge is largely based on descriptions, imagery and comparative cross cultural studies.
