Cumin seed, both ground and whole, turmeric and ground coriander seed are the holy triumvirate of Indian cookery, most dishes incorporate them as well as other spices particular to various regions. Turmeric, BTW, is purported to have anti-cancer properties, we put it in our daily salad dressing. I am quite partial to Indian food and make it regularly. Many on-line sites with recipes -- I have two cookbooks which I use.
