Another enduring ritual that I can think of is reserved for smokers. There's something truly lovely about excusing oneself during a natural break in conversation to step outside into fresh air, and inhale deeply for a few minutes. It almost makes me envious of smokers.
Our instructor brought up ritual to caution us future doctors to be careful when we recommend smoking cessation or removing coffee consumption from our clients' lifestyles--we could inadvertently be removing something much more sacred to our client than just the substance. We can suggest, she pointed out, that our clients create new rituals with new, intentional meaning. Or maybe, at the right time, for the right person, tobacco leaf or coffee bean--two truly weary and abused herbs--can be replaced with another underappreciated, and eager herb or two.
