Really? That would mean 12 cloves of garlic, 3 chillis and 6 teaspoons each of cumin seeds, curry powder and turmeric powder which seems an awful lot!
I do understand what you're saying, bandit2004, that if you put x amount into one portion then it shouldn't matter if you multipy by 6 as it's no different to cooking individual portions and mixing them, but 6 teaspoons of the spices mentioned above does seem rather excessive and I don't think I've ever seen a recipe requiring that much - even if it is for half a dozen people! Perhaps someone can explain the science behind scaling up recipes?
