I think the difference between the punjabi sikhs and the 3ho sikh are, that the ones from Punjab try to become as western as they can and the 3ho are performing the more "orthodox "look.
In my local Gurwara almost all women have a haircut or dye their hair with henna, wear make-up, jewlery including nose and earrings. They explained it to me like this, that it is a sort of showing off how wealthy and liberal you are. But there is also a amrithari that doesn´t wear make-up or jewlery apart from her kara and a dastaar. She´s also the only one with cotton fabric clothes, the others are more up to colourful synthetics with rich embroidery.
As I understood the original message, you shouldn´t be attached with worldly things like jewlery or even looks. The message is clear that the way God made us is perfect and a sikh should respect that by leaving the body like it is, including kesh, not making holes for ear and noserings or other piercings.... (I myself have a nosering, a little one, that I have had for over 10 years now. It feels so natural to have one that I don´t take it out. The hole would be there anyway.)
Another thing I´ve seen at the Gurdwara is that many sikhs, even the elderly ones have tattoos. Mostly an ek ongkar on the forearm or the hand. This is something you shouldn´t do either. But I guess their thinking is, to mark the body as Wahegurus or to have it as a permanent kara?
Most of the punjabi sikhs seem to live quite a dubbel moral. I was told how got a belly piercing from their husband for birthday or that most of the amritharis there drink alcohol and eat meat (quite controversial anyway if you should or not, I know) and from time to time take amrit again to quite drinking for a while.
I was at first a bit surprised and even dissapointed by the fact that Punjab is one of the states with the highest alcohol and meat consumption in India and the highes male/female rate...meaning the state with the highes female foetus abortion rate.
Some weeks ago I was invited to a very nice punjabi family that went immediately to show me weddingvideos. Almost every man wore a dastaar, most had trimmed beards and all but a few drank whisky. I asked them why they wear dastaars and look like sikhs but don´t behave like sikhs. The answer was, that the dastaar to most of the punjabis is more a cultural or traditional thing and doesn´t represent one´s religiosity.
For me it is actually more about dettachement and purity, but I still sometimes wear nailpolish for example, but I´m no amrithari either. I think that people converting to sikhism may feel more attached to the idea of purity and divine perfection of the body than the ones born into this belief. `Cos we chose to live that way.
And it shows that we are all human.
What do you think?
