Hasidim lend great importance to "kavana", devotion or intention, and their services tend to be extremely long and repetitive. Some courts nearly abolished traditional specified times by which prayers must be conducted ("zemanim"), to prepare and concentrate. This practice, still enacted in Chabad for one, is controversial in many dynasties, which do follow the specifics of Jewish Law on praying earlier, and not eating beforehand. Another reglement is daily immersion in a ritual bath by males for spiritual cleansing, at a rate much higher than is customary among other Orthodox Jews.
