Do you think the reason intoxicants are banned for Khalsa is because they are supposed to be ready for trouble at any moment?
If I am a soldier-saint, and I'm tipsy or drunk, I'm probably not going to be much help when that dude attacks that other dude over there, right?
Wouldn't that be the logical reason why intoxicants are frowned upon? A Khalsa is meant to be ready nearly 100% of the time. Being drunk = not ready.
And since the line between having a drink and being tipsy is blurry, it would seem best practice to not drink at all.
I think the natural human state is to become intoxicated very quickly. You have to drink and become tipsy to build up a resistance to the effect. That's why I can drink one glass of red wine and feel okay, one and a half and I am tipsy, and my partner can drink a deal more (he's been drinking a lot longer than me).
At least, that's my theory on alcohol.
I guess it can be applied to anything that alters the state of mind. Sleeping pills, medicinal marijuana... Pain killers don't really impair your functionality... You have a migraine that is affecting your ability to see... someone breaks into your house, you are at a disadvantage. Alternatively, you have a migraine, you take some pain killers, they might make you feel pretty good but when that bad dude comes through your window I'm sure you'll have better aim with the golf club.
Now, the question is, if you're incapacitated (is that spelt right??) anyway, is there any harm in taking something mind-altering that will make you feel more at rest in your already-incapacitated state?
Shouldn't it all come down to logic, and the logical reason why we should or shouldn't do things?
