1. Don’t carry toilet paper.
This is essential, especially if you just cannot live without toilet paper. In India, usage of toilet paper is pretty limited — you will find it available only in hotels, malls, and just a few homes. And if you ask why we don’t use toilet paper, I would let Shivam Mishra answer it.
2. Refuse a religious offering like Prashad.
There is no such thing called ‘Refusing a Prasad’, because no one does it. Prasad is considered God’s blessing, something that purifies you once you eat it. Obviously you wouldn’t go to jail for this, but you could definitely offend someone.
Also, just so you know, a cow is a holy image in Hinduism and their excreta is equally auspicious. So you better not give a disgusted look if you see huts anointed with gobar (cow dung) or a Pandit sprinkling gaumutra (cow’s urine) around for purification.
