Are Sikhs forbidden to shake hands with a person who smokes tobacco?
That's interesting. Are there any other customs in Sikhism that involve physical purity?
Yes, Sikhism emphasizes purity of the mind and body. For example, Sikhs are required to keep their hair uncut as a sign of accepting God's will. They are also expected to bathe daily and wear clean clothes.
